research to see if i can run x without a video device:). Maybe have a look at Xvfb ?

Therefor the security between host and vserver is not first goal. 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. -- Funny quotes: 30.
