NX doesn't compete with LTSP.  NX is nothing like LTSP.

LTSP is a distribution of linux that runs on thin client hardware.

NX is an X proxy that works very well over low bandwidth connections.

#1 is correct. LTSP loads over the net.

#2 is also correct, but then again, operating systems
   run in ram on all computers.

#3 is sort of correct, but it's not complete.  One of the
   things you can do with LTSP is run an Xserver with
   and XDMCP query to a server.  you can also run rdesktop
   as a session, without doing an XDMCP query.
   You can also run a character based telnet session, if you
   don't want/need a gui.

NX is a very interesting technology, and basically, there's
only 2 reasons why it isn't in LTSP yet.

1) Until now, there hasn't been a free server available.

2) There's only so many hours in the day.

With Freenx, it appears that we now have a free implementation of the NX
server technology.

So, the only remaining hurdle is finding the time to integrate the NX
client into LTSP.  I've not spent any time at it yet, but it really
shouldn't be all that tough to create a screen_script that
runs X and the NX client.  Anybody want to take a whack at it ?
