Can you broadcast to a Shoutcast server from Android?

I run a shoutcast station for a small group of people. I would like the ability to broadcast to my server from my phone so that I could do live broadcasts away from home. So far I have not found any software to do this, because searching only yields ten zillion results for streaming radio apps for listening, not broadcasting. Someone I asked tried to suggest that it was not possible to stream efficiently over a 3G connection, but frankly this is rubbish because I have streamed to my server from my laptop via a 3G stick before, and on my phone I have streamed audio and video to services like UStream etc. Does anyone know of any software for android capable of broadcasting to a shoutcast server ? Thanks.
