Just back online after OSCON. Reading/replying on this thread one at  
a time.

I've been wanting to try that as well.  Pretty much for the same  
reasons you mention (more utilization, more test results), and also  
that we could maybe start getting certification numbers for other OSs  
depending on how we did it.

Obviously, the "other OS" concept would require VMWare whereas we  
might get away with just Xen if we simply wanted to expand our number  
of test hosts.

To my memory, 512 isn't enough.  I seem to recall 1g being the  
general, finger in the wind, of size.  We could experiment as it has  
been a while and our server has changed a bit.

Testing boxes don't need public IPs to test, we just need some way to  
get in to admin the box.  As long as we can do that we're golden;  
forwarding or tunneling should work.
