I prefer NX over VNC because of its efficiency, and because it is more
intelligent, but I think it has no mode to let two people access the
same session at once. So I (being remote) tried starting a session with
NX, running KDE, which has a VNC feature, so the other person (with the
session runnin in his fast LAN) could attach via VNC. But tit did not
work well due some color bug.

Setting a forward route with iptables would be the standard idea I'd
think. But I'd probably just set up an SSH tunnel, like this:

ssh -R :5900:localhost:5900 debian-server

So when someone connects to port 5900 on the debian server, the traffic
is forwarded to port 5900 on your machine, which would run the VNC
session. If the session should run on the non-linux guy's PC, he should
start the tunnel using putty or something. See the ssh man page and the
-R option.
