We are working on something similar for a project at work also.
We are using ZeroConf ( aka formerly Apple Rendezvous now Apple Bonjour ) 
for cluster discovery
and a Perspective Broker interface for exchanging information.

We considered reliable multi-cast but decided against it because our 
clusters are not going to be very big and
are going to use a kind of inversion of control pattern instead of 
distributing all the data everywhere.

But I am interested in a COMMON IDIOM for clustering twisted servers, I 
would definately say ZeroConf needs to be
the discovery mechanism, no need to re-invent that wheel and a Twisted 
implemenation is easy
