The first randomly selected audience winner today at the RealTime CrunchUp is SuperFeedr . They are an API service that works with both XMPP and PubSubHubbub (which launched at the frist CrunchUp) to create realtime content feeds. As they noted on stage, it's hard to demo something that is API only, but one implementation that we've written about before is Excla.im , which we wrote about recently . This allows for the realtime tracking of keywords on Twitter via IM. But this idea works for all content.
