Yes FC1 does use TCP ports for X11.

Display :0.0 = TCP port 6000

XDMCP does not use TCP by default, so you can't access a remote desktop
but the display is still listening. You use xhost to control access to
the display.

If you log onto another machine and export DISPLAY=yourhost:0.0 and you 
have run xhost +remoteip then when you run an X app on the remote 
machine it will display on your local interface, you also need to open TCP port 6000 in your firewall. You can also use ssh forwarding to 
simplify some of the steps and encrypt the X commands between the two 
machines, this does not require TCP port 6000 to be opened.

I use ssh X forwarding all the time, and it works well.
