Playing a PC from another room

I have a good gaming rig in the other room, and i want to connect my monitor, mouse and keyboard to the PC in that other room.

Basically what i want is that 2nd person can use internet on the other monitor with the 2nd mouse&keyboard while i play games for example on the 1st monitor.

What do you think? I'm already using a PS3 from another room and sound has no delay, so i assume keyboard wouldn't either on a PC?

not practical. just buy a cheap computer for office use

No, i won't buy a cheap PC for office use, it's not my PC, i'm the one who has an office PC and i can't just take someone elses PC, can i?

Why isn't it practical would be more useful to say.

Also, i need 2 sepperate cursors for 2 mice, is there any working program that allows this or are people still retarded and can't think of why its useful?

it's a problem of multitasking. while you're loading up all those xtreme fx the dude trying to collate database records will be a little mad and so will you. plus, one might move his cursor over to the other screen, happens a lot when games don't accomodate for multiple monitors (for example, a lot of RTSes you'll be wondering why the camera isn't panning - it's because your mouse is on the other screen).

the problem is that a cursor cant be in two places at once.. thats the dilema you face..
