... A similar thing was done with AlienBBC and RealAudio streams (I
think its changed now as BBC don't use RA any more). The stream was
transcoded on the server by AlienBBC calling some libraries - I don't
know if this meant a DRM was involved or just a CODEC as I don't have
anything using RA (apart from the AlienBBC plug-in) and know little
about what the it or BBC did.

Also I believe that in the past QT libraries have been used to bypass
the DRM (by extracting the bitstream after decryption and re-saving the
un-encoded AAC back into the container) so it might be possible to take
a similar approach and capture something downstream if its available
and pipe it/transcode it over the n/w.

Such an approach does not require DRM on the SqueezeBox, and since the
SqueezeCenter software transcodes some file types anyway this is
exactly how it already works.

Since streaming FairPlay music isn't more common I can only assume
getting at the unencoded data before its passed off to the D to A
hardware is actually pretty tricky, and I suspect "songbird" just does
what several other music players on the PC platform do and just call
the QT libraries pass off the file and rely on them doing the necessary
all the way to the speaker :-)
