OK, good point, that's not going to be something you'd want to do as 
part of a short term plan. And without it we'd have to have radvd 
running ourselves, so we're almost back to the starting point (except 
for not having to maintain the uplink ourselves, including worrying 
about things like not disturbing the VoIP setup).

Most likely nobody if it's a single VM. But currently _all_ buildslaves 
start heavy work at exactly the same time. That's 4 buildslaves (soon 
even more as we don't have Ubuntu Karmic and Fedora 12 yet) against 1 
Asterisk VM.

If there's a reliable way to do so, I'm eager to hear it. Didn't even 
manage to allocate sufficient resources to my MP3 player software at 
home. Process priorities (nice level) isn't enough and giving the MP3 
player RT priority makes it even worse.


PS: Please respect Mail-Followup-To. I'm already on the list.
