Jean-Marc's reply covered what speex needs; for iLBC I can only say
that I think I recall that it takes less than g729a, and the latter
is supported on the zaurus (200MHz strongarm)....

Once converted to fixed I'm sure speex will be fine on strong arm
and intel's newer stuff based on that (pxa?).  It might even work
on the arm940 (12MHz); if so that chip should be enough for an IP
phone with 711/rgl/ilbc/gsm/speex support.  I would love to see a
802.11 phone like that, complete with a tiny price. :)
