Why Winaxe and not cygwin/X ? It is free and pretty easy to use.

BTW, whatever X-workstation you use on Windows, disable the personal firewall if you want to do 'X -broadcast'. If 'X -query <ip>' is fine for you, just open the 177 UDP/TCP port on the PC. After doing this, I can run all those applications on my Xbox through cygwin/X on my PC.
