Forgive me, I don't normally gush like this but FreeNX warrants it . . .

I love FreeNX! The RPMs installed easily on SL41 and performance is 
nothing short of amazing. I can remotely run a KDE session over a 768K 
DSL line and it's almost as fast as sitting in front of the machine, 
fully as good as Windows Remote Desktop, maybe even a little snappier. 
FreeNX binds to the SSHD server so communications is a no-brainer. There 
are Windows clients available to so it's great in a mixed environment.

OpenGL screen-savers like "Atlantis" even work over DSL!

Oh, and to speak to the original question; you can indeed disconnect 
from a running session and reconnect later.

Linux Journal has been running a series of articles on the subject:

OK, I'm done! ;-)
