While I think RealPlayer on the PC acts more like a virus than anything else, it is important to recognize that there are a lot of things out there that are streamed in RealPlayer format and nothing else. I personally think it's a substandard format (Especially with video. Man that sucks), but it's been around the longest and isn't going away anytime soon.
Real AUdio pretty much sucks but I use it
I was able to get a hold of a beta of teh producer software when it was public betaed and have been using that since to produce my files.
