	there are efforts to make X-over-IPv6 possible, including:
	- old patches from INRIA
	- recent patch from Sun Microsystems
	the latter is considered for inclusion into X11R6.x (or R7?).

	the issue is that X is not using sockaddrs right (they use "int" to
	hold IPv4 addresses, IIRC) so it needs a serious cleanup before we
	actually make it IPv6-capable.  the good thing is that we need to just
	change some libraries, and we're done.

	for the time being, you can use ssh X11 forwarding....
