iTalc
Intelligent Teaching And Learning with Computers
iTALC is a […] powerful didactical tool for teachers. It lets you view and control other computers in your network in several ways. It supports Linux and Windows 2000/XP (Vista support will come) and it even can be used transparently in mixed environments!
Control / view / manage many machines from one machine.
Convert Your Workstation To Windows Server 2008
For those of you unhappy with Windows Vista, but unable to purchase Windows XP anymore, here's another option — assuming you don't want to (or can't) buy a Mac or switch to Linux, obviously.
The only downside to this, of course, is the price. The cheapest I could find WS2008 OEM was for $628. That comes with 5 CALs, but you won't be using those when you set up your workstation.
So, without further ado Convert Your Workstation To Windows Server 2008.
