Help with online radio station?

[gruffaloman]

Im thinking about starting an online radio station with two mates, using shoutcast, and i was wondering how to do it if we were in different places? I would be at my house streaming it and with the mixing desk/software, and one mate would be talking at his house with a mic, and another mate at his house with a mic. Is there any way that i could get thier audio, live, as an input using some software or website or other streaming?
