That's enough to make the vserver insecure.

If your X11 is exploited, you're toast, so you can as well run X11 from
the host and make it contact the xdm running in the vserver.

Off cause this isn't as flexble as running in the vserver, but unless
you're testing different X-Servers, this should be a minor problem.

However, I don't know if 3d support is network transparent, and I can't
test it here.

    drives a race car not called a racist?
