In fact, it's quite a similar concept to Emulators and VMs. Except of course that your idea pertains to something built-in to the OS and not as a separate application. And the implementation might be technically different too... It might be possible.

What would be the effect of memory/processor usage? Would you need extra memory to run the extras? So this would be like having every pc be it’s own terminal server?

In terms of memory/CPU usage, I'm not really sure, but it shouldn't be too much as you are not really emulating the system but sort of 'copying' it over. <blockquote> Would you need extra memory to run the extras? </blockquote> We'd probably need a memory boost of sorts when copying over an application - that should be as quick as possible. The permissions model would give you better speed for less RAM, but also if the write/execute permissions are played with by a cracker then they could still 0wn your system. Hmm....anyone wanna take this up? ;) Hehehe... Hi Ray - in a sense, yes.
