The MP3-over-RTMP (in flash) was the first step of getting Listen Again on the iPlayer. They plan to migrate to AAC+ (possibly starting from this month) because it is already supported by flash player and is more bandwidth efficient / higher quality. The mp3 streams being used in the BBCiPlayer plugin were intended for the Apple iPhone which does(will) not support abobe flash player (The plugin has to fake an iPhone user-agent to get these mp3 streams). It was my suggestion that these streams were just a different transport mechanism using the same files served over RTMP/flash because of the similarity of the bitrates. It would seem from all the blog and forum stuff I've read that the MP3 streams will be dropped once they are happy with AAC+ and I reckon that the mp3 will then cease for the iPhone streams because there is no logical reason to keep mp3 for the iPhone when the more-apple-friendly AAC+ files will be available. They don't support any more devices with Listen Again mp3-over-http AFAIK - just the iPhone. So in future, if this transition happens to AAC+, transcoding (e.g. mplayer) will be required unless the SB can get AAC+ suport in the firmware.
