I won't say that it's impossible (nothing is impossible in the Open
Source world :p), but I can't see any easy way of accomplishing this.
VNC uses (AFAIK) a rather simple authentication mechanism, but the
NX technology uses SSH (with pub/priv key) + user&password.
"Reversing" this mechanism doesn't look (to me) to be a simple task.
You would also need to make a custom client (look at the FreeNX Client
QtNX for GPL'ed code) that would accept the connection from the server.
Maybe I'm looking all wrong at this; a simple program (on the
server) could send a special command to a custom client with info
about the server/IP that it (the custom client) should initiate a
connection to. That might be a more probable workaround to it...
My 2 cents :-)
