I don't know if this is already done in NX or FreeNX (I'm quite behind with 
following the very active development) but the way of doing what you want is 
having xdm (the flavour you're using, i.e. flat xdm or gdm or kdm or 
whatever) start your local session as an NX client first. Then when you go 
home, you live your session on or you suspend it, but you don't close it. 
Once at home, you make a session request to the same NX server on which you 
had your session opened at work and the server will either suspend an already 
existing session and give to you the control at the distance, or will just 
reactivate a suspended session.

Well, there are two issues with this scheme right now. I don't think the 
session managers (xdm, gdm, kdm) have already support for NX. (But this can 
be worked around, I didn't test anything, so I'll leave it as an exercise). 
The other issue is how well "roaming" sessions (ones that can be opened from 
different locations at different times) work already. Didn't test that 
either.

As you understand, NX can't take a normal X session and export it at a 
distance, because it would need to hijack the X protocol communication 
between the X server and the local display, which I don't think is a feasible 
thing (not with the technologies we have right now).
