Maybe not the typical desktop user but that's definitely not going to be 
the case for the enterprise user.  I do a lot of testing with small 
domUs and I routinely have 40+ domains running (16MB a piece) on my 1GB 
laptop.

On a 4GB system, with NFS in the picture, you could pretty easily 
exhaust the privileged ports with domains using between 32-64MB of 
memory (which is a pretty reasonable amount to allocate).  Throw in PAE 
support and you'll run out quickly.

Would a patch to change Xend to use pty's for consoles be accepted?  xm 
console can be invoked via ssh to support remote consoles..

I hate to beat a dead horse, but domain sockets seem like the obvious 
thing to do.  We don't need different privilege levels there so that 
seems like the thing to do.
