While its name may be less than meaningful, Perspective Broker is an extremely easy to use Remote Procedure Call library. It leverages the excellent Twisted asynchronous framework to make it really efficient to communicate between processes, be them local or remote.
The talk will start with an overview at other common RPC systems (XMLRPC, RMI, etc) and show some of the common issues that may arise while using them, and how to forget about those by just using Perspective Broker. Some usage example and use cases will follow.
