Is it possible to do X forwarding over bluetooth?

[Han]

Hi,

I wanted to do X forwarding over bluetooth connection. I tried with
using SSH X forwarding over bluetooth PAN.  It worked but it's slow
and complex to setup. I am wondering:  does X forwarding require IP
network address?  Is it possible to do X forwarding directly over
bluetooth?

btw, I can write program to create socket directly over bluetooth
without using PAN.

thanks
