I've been in contact with the people that are making O2 skiing (http://www.o2skiing.com) and they've given me access to their code so I can port it over to mac. After about 5 minutes of checking out the code it looks like I should be able to get it up and running pretty quickly. I can't say for sure though. I'm pretty excited about it and I don't have school this week so hopefully we'll see some progress. I'll keep you guys updated.
