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
