Wow, really?

Beyond distcc, I looked at cluster based approaches but they all  
leverage distro repositories. Basically you have a "master" node that  
hands out work to "slave" nodes which start out all using the same  
filesystem, the master works otu which packages it can build with out  
dependencies and hands them out to the "slave" nodes, which build them,  
create a binary package (.rpm, .deb, the portage binary thing, etc) and  
sends it back to the "master" node which loads them into the  
repository. The master then hands out more work to the idle slave nodes  
using only packages which have prerequisites that can be installed from  
the repository rather than built.

(I looked into having them all share a network root filesystem and  
having the master node update it, but running ./configure while a  
package shows up out from under you is kinky.)

I also covered setting up tun/tap for kvm/qemu here:

(That covers more than you'd need, but if you have a 4-way machine you  
can get a small cluster setup that way, and each qemu instance gets a  
cpu to itself...)
