Twilio Client - New VOIP API for Javascript, Android and iOS Apps

I've been looking for a good reason to use twilio for years now. Will the latest developer contest with this new API http://www.twilio.com/contests/2011/07/new-developer-contest... be enough to get me to look harder? I think it may.

Lets hope this moves us towards having a simple data based billing system for mobile devices instead of charging per minute/text message.
