you could hop on irc.freenode.net, /join #celt, #theora, #speex and/or
#xiph and see if derf (the presenter in the link i posted) or jmspeex
(jean-marc valin, the remote end in the celt presentation) are around,
and discuss it with them directly. alternatively, maybe torben reads
this and picks up the thread?
