Not sure, I can drop him another email. He's a professor at Carnegie Mellon, he does the Cepstral stuff in his free time. He seems partial to the ARM platform (he released v1.1 of flite wth ARM binaries) but more so due to the iPAQ. He didn't seem to have as much zest for the Empeg as the guy who's giving us a free Vorbis license, but I'll see what I can work out.

The problem is we'd need source code so we can graft in sample rate conversion and native use of the Empeg's quirky sound buffer. Not sure we'd be able to convince him to develop a custom Empeg version of Cepstral due to its sample rate/buffer size quirks.
