A New? Idea

Question about which tools to use, bugs, the best way to implement a function, etc should go here. Don't forget to see if your question is answered in the wiki first! When in doubt post here.

And I thought very usful.
Then you have to buy hardware to support the two mice and two keyboards and two monitors on the local machine along with an OS that supports the same in different sessions. Then, what happens to these companies when their only PC crashes? Guess you need that only one to have server hardware and fault tolerance. By that time it'd be cheaper to buy two different low-end PCs than to have that setup considering you can buy decent PCs from major manufacturers for about $600 or so.

That scenario might be neat to toy with buy don't know if it would fly in the business world.

Just because you do not see a value in this guys idea, does not make it bad one...It almost sounds like your making stuff up to put the idea down? Like exactly what extra hardware do you need to buy? ( other than KB, MOUSE, Monitor & VGA card). And server hardware - ya right - give me a break - that is all a scam. My PC is way more stable then most of the servers in most of the places I have ever worked. The only trouble I have ever had was when I had dual CPU motherboards (server class boards). I gave up buying those a year ago becuase both of them burned up on me in exactly the same manner. One was a BP6 and the other was an Intel board - I can't remember which model. I guess server class means that they just cannot be run at room temperature like most PCs - you need a dedicated server room with extra AC and de-humidifier.

Actually it brings up a nice question, one I considered a while back.

How much hardware does one user actually need?

I figure they need (Minimum) a monitor, keyboard and mouse.

The server needs a few more things like a printer etc.

Now let's say you use wireless mice/keyboards on different frequencies. It'll be less responsive, but not so bad you couldn't live with it.

Ok, so interaction is solved, how about the monitor? I figure you could build yourself a board that contains very little aside from a low end graphics card and some wireless hardware. Then have the server do exactly the same thing it's doing with the mouse/keyboard with the user's screens (Ie just send the data wirelessly).

So you've got mouse, keyboard, a screen and a little box that sits on the desk (Which could even be incorporated into the monitor if you have the dev cash). Frame rate would be quite poor, but if you're talking about an office environment then just how high does frame rate have to be? I figure you could run a fair few users off one server with that system, it would be a question of processor speed/bandwidth more than anything. Interesting idea, perhaps more inline with the original MULTICS concept than anything currently in production.

Wow. I've not heard/seen anything about this kinda thing for 5 years. An older library that I used to go to had this kind of setup. Worked fine, and cut down the costs for them(they were just for browsing the library cataluoge anyway).

I'd love to see something like this implimented on a "modern" OS. However, I'm unsure how the keyboard will work, as there is only one keyboard controller(normally) on the motherboard. You would need one for each keyboard to be able to not get scancodes mixed up.

Does a USB keyboard go through the keyboard controller? I would not think so as the whole point of USB is to take the smarts out of hardware and put it in software. But that is just what I'm guessing - I do not know for sure. I've got a half assed USB driver worker, but have not got far along enough with it to really tell what the keyboard does yet.

Anyone?

USB keyboard usually have an "emulation mode" that can be activated through the BIOS so that it can behave like a legacy 0x60 keyboard ...

Thats right most computers have more than 2 USB ports and the standard PS/2 ports for so its highly fesible that you could have your standard PS/2 devices and the USB Mouse and Keyboard. It wouldent even mater if the BIOS didn't understand the USB keyboard becuase you could have one PS/2 keyboard attated any way.

Or you could just attach two USB keyboards. Or maybe fifteen.

Well thats the idea. Also you might not have to buy a new graphics card seems most midrange cards have two outputs.

they have 2 output, but are they available to use both simultaneously ? and are they able to send distinct images to both ?

The other thing is lots of cheap motherboards have AGP built on. Adding an additional PCI card is pretty cheap.

Pype, yes and yes. I'm writing this on such a creature.

Pype, soap is right two outputs onto two different screens with two differnt images is entirly possible. However I havent yet got it to work in Linux. My laptop which i'm righting this message on can be connected to a extra monitor or the TV. And display differn screen on each. You must note though I'm not saying I have 3 outputs. You can either use the TV or the moniter. Or both with the same picture on it.

I think, you are talking about the technique, known as virtualization, has been possible in the mainframe world for years but is now becoming a more viable option for Unix and Intel platforms as IBM and Sun Microsystems prepare to roll out products. Also boch, VMWare, Connectix provide virtual machine with virtual machine, modification in Boch, that can provide base to you.

Here are some links you may find interesting, of course, you can search google :
