Wanted: GSM decoder SOURCE

In order to listen to audio broadcasts like the one just announced by Daniel Karrenberg I need *source* for a GSM decoder. I understand that VAT includes GSM but it seems to be available as a Sun SPARC binary only, while I can only use SGI Indigo workstations. I read the mbone FAQ but it gives no further clue. I would prefer a clean set of subroutines that do just the decoding work (so I can program the network protocol and audio user interface myself -- I can use code that I have for other encodings) but I'll take any solution that I can get working in time to listen to the Prague meeting. Of course I wouldn't mind having a GSM *coder* so I can test my decoder :-) --Guido van Rossum, CWI, Amsterdam <Guido.van.Rossum@cwi.nl>
