Feature Request: Add Message Bus to Boca

[GoogleCodeExporter]

Hi 

I'm interested on working on different clients to publish information about the 
contest - following the rules of the Tournament - and it would be helpful to 
have a Message Bus, where my clients could connect to have real time event 
notifications for  important events, like when a problem was solved, when the 
contest was stopped and so on. 

I'm willing to help with the implementation details. But i would like to 
discuss first if is a good idea before starting to code anything.

Thanks
