[expert] "Fast user switching"

[Olaf Marzocchi]

In Windows XP I'm are able to switch between users without closing the apps. With enough ram (I have 256 MB on my p4 1800), the whole thing is fast and pretty useful: you don't have to close apps (when I surf I keep open at least 7 windows and/or tabs) and both people can work inside their environment.

I'm planning to let use my linux bos to anyone living with me, so I'd like to know whether a similar feature exist or not.
I already know I can start xfree many times, but I don't want users to be able to switch from an xfree to another one without being asked for a password.
Moreover, each xfree instance requires a lot of memory.
Another option is to log out every time and tell the WM to save the session, but when I come back every app has to be launched again and it takes time (remember, I'm going to share my cel400!, not the P4).

Could you suggest me a solution?

Thanks
Olaf
