Hrm. wireshark (running in promisc mode on my desktop that runs cygwin) 
does show TCP sessions for port 6000 (that's X11, right ?). But somehow 
that doesnt seem to get through correctly. I tried opening up that range 
on my desktop firewall (Norton Internet Security), but that doesnt seem 
to change anything.
