As luck would have it, the GSoC application period just got over !! This means
that I haven't submitted an "official" application for this to FFmpeg. I have
instead applied for the G.723.1 decoder and encoder as far as my inclination
towards speech coding goes. But still, speex support (or anything else for
that matter) and related work can be done outside of GSoC as well and I'm
glad that the speex author himself would be available for answering questions
regarding the source. I'll surely look into this (or assist if anyone is
doing so already) after I finish some stuff I'm researching for the alac
