As I've state before, we expect that you can run about 100 machines per
registry server.  We do, however, expect that those registry servers are
running on server nodes - not nodes in personal use.  A slow machine 
(e.g., dn3000) with a reasonable amount of memory (>= 8 Mbytes) should do
just fine.
