cfengine 2.  Actually, I'm just starting to work on this.  I'm tired
of sshing things around.  It worked so nicely when I worked at the
IMA, and I've missed it ever since.  The number of boxes we need to
manage keeps rising, ssh pub/priv keys need to be managed, X.509 ssl
certs and keys need to be pushed.  Etc.

cfengine is one of the most effective ways to manage your network.
There's a bit of overhead and learning curve, but once it's in place,
you'll never understand why you tried to manage a network without it.

Create a Xen guest that acts as the cfengine master and the other
guests as clients.
