We are working on something similar for a project at work also.<br>
We are using ZeroConf ( aka formerly Apple Rendezvous now Apple Bonjour ) for cluster discovery<br>
and a Perspective Broker interface for exchanging information.<br>
<br>
We considered reliable multi-cast but decided against it because our clusters are not going to be very big and<br>
are going to use a kind of inversion of control pattern instead of distributing all the data everywhere.<br>
</div><br>
But I am interested in a COMMON IDIOM for clustering twisted servers, I would definately say ZeroConf needs to be<br>
the discovery mechanism, no need to re-invent that wheel and a Twisted implemenation is easy<br></div><br><br>-- <br>If you don't know what you want, you probably need a nap.
