 thanks alejandro - no i kinda set my heart already on a leaflabs
maple, because the team there have been so helpful already.  what
*has* been really useful on there is reviewing the various peripheral
boards.

 this is a *great* find.  source code and datasheets as well,
fantastic.  that gives 2 choices of camera.  the TCM8230MC was the
other one that i'd found (from sparkfun)

ohhh, my faaavourite - i remember the UDA1380.  when oiii were a
laaad, oi dreaamed of getting that f*****g thing powered up on the HTC
Magician bloody hell it was a baarrrstud, it werrr :)

 no, seriously: although the IC was absolutely fine, we *just*
couldn't work out the GPIO power-up sequence + I2C + I2S sequence and
settings.  it didn't help that there were other HTC devices (Compaq
iPAQs) that worked absolutely fine, that just drove us even more nuts
:)

 thank god i don't have to reverse-engineer any hardware for this
project, eh?  awesome....
