How does NX compare to simply using SSH to compress the tunneled X
traffic?  If NX can safely eliminate round trips to the server, then I'm
all for it.  Why is it not a standard part of X11 if it can do such a
good job of eliminating round trips and compression?  Any remote X
displays (even on a fast network) could benefit from that.
