Ah, so the data in the jitter buffer should still be a pure speex 
packet? I thought one of the reasons for moving away from 
speex_jitter_blabla was to make the jitter buffer more generic? I'm 
currently using 1 byte before the packet for metadata which accompanies 
each and every packet. I could move that to in-band user data as well, 
but that would mean it's 2 bytes instead of 1 :(
