Ive been now trying the Remote Process Explorer that Roy posted and i have to say that im impressed. I had quite a bit of fun with it. The best functionality i saw was the ability to log off and shut computers down.
Tubs commented that is not realtime view, but its very very close to it, you can choose the refresh time according to the priority of the process (high, every 2 secs, etc.)
The only thing that i couldt really manage to do was to run a process, the process run but for some reason it doesnt pop on the users screen.
Apart from that i would really consider this program.
