There is a build speed trade off, but when you add up the time and
resources to cvsups a bunch of individual machines, this is usually
more efficient. I have done this as well.

The way the system works now supports this. You should have a separate
configuration file for each machine's kernel in
/usr/src/sys/i386/conf. When you 'config' a kernel, it creates a
separate build directory for _that_ kernel. You could actually build
kernels simultaneously on multiple machines with a single NFS server
with the "real" /usr/src/sys, and it should work just fine.
