Theoretically NX can do a 'shadow' session where the client connects to 
an existing current connection, and as a special case, this can be the 
console.  However, I've had trouble getting those connections to work at 
all (I think the size and color depth has to match exactly or something) 
and when they do, they don't really perform any better than vnc anyway 
and you can't resize the desktop to match your local screen.  So, the 
way to do it is to start the session under NX to begin with.  There's 
some overhead if you do it on the local machine but except for playing 
video it shouldn't be enough to notice.  But if you can run your session 
on a faster server box that is noisy enough that you don't want it at 
your desk - or you have a slow/cheap box at your desk, or move around to 
different machines, or need access to a different OS, it comes out as a 
win to run everything that way. In my case I generally park it filling 
one screen of a dual-headed windows box.  And even those things don't 
apply for your main work, you might park a session on some 
well-connected machine that you can reach remotely through vpn or ssh. 
Then a single client connection to that gives you access to both 
whatever you left running there and all of the internal machines it can
