I had a look at the radio pages. Looks good. Is there any particular 
reason you chose Shoutcast over Icecast? Are you using PD solely for the 
mp3cast~? Or is it doing more than that? Are you using the GUI's for all 
of these (jack, PD, jack-rack, xmms)?

 From what I understand, ffserver is used for the flash version, right? 
I haven't really heard much about flash stuff, I personally dislike 
flash and I don't even have in installed.
