Oh, I didn't realise they haven't been released yet.  I assumed that
considering that firmware is available for download it was available
immediately.  I ordered mine on the 6th with 2 week delivery so technically
it's not late yet.

I misread the DSerial Edge wiki page, apparently the RS232 level converters
were taken off, but making a box with them in shouldn't be too much of an
issue.  Whether host USB will be possible remains to be seen though.  At the
least it will require an inverter to get 5v (although I have an inkling that
these are builtin).

The preliminary microphone code is in SVN now and although it works, it's
not exactly usuable at the moment.  I'm in the process of porting SoX to aid
sample conversion:
