I use contrib/monotone-cluster-push.lua, with a cluster-push.rc having
the following content:

  pattern "net.venge.monotone*"
  server "monotone.mtn-host.prjek.net"

  pattern "net.angrygoats.viewmtn*"
  server "monotone.ucc.asn.au"

I haven't tested it that well yet.
This requires an exchange of server keys (the one pushing has to send
the server's public key to those he/she is pushing to).

If you want, I can set up a push to lapo.it as well, and let's try
this baby out for real...  especially with the new key format, I
suspect there will be some rewriting to do ;-)

Cheers,
Richard
