I know I posted the website earlier in this thread, but atdhe.net is an awesome website to stream sports. A lot of times, they'll give multiple links for streaming (not just sports, either).
I was using Skyfire to stream the Lakers game, while we were attending a wedding and it was working perfectly, while I still had battery. Thankfully, since the Lakers were getting a beat down, my battery went dead, but we were able to watch the 1st quarter on 3G and it worked great (not much lag)!
I seriously can't wait to see how it'll work on the EVO!
