Yet Another Message Broker (yamb)

This package contains yet another message broker (several, in fact), allowing experimentation on how an application would use messaging. The current main attraction is amb, the Abstract Message Broker API, which allows seamless transition between messaging backends. Meanwhile, tmb is an absolutely minimal message broker that nevertheless supports both native and web apps, and can be used as a baseline tool for doing integrated testing of messagebus-dependant apps. Combo it with amb to allow the deployment to scale to a real message bus and there's something there!
