Well controlling the N900 camera is reasonably straight forward using
the gst_photography_*() commands, I'll write up a page and stick that on
the wiki asap.

I've moved the backend (i.e. the decoding part) to use zbar for 1D and
QR codes and am still using libdmtx for Datamatrix codes (would be nice
to get that linked in as part of zbar so there's just one api to deal
with). I also just uploaded the zbar files to the autobuilder (and it
failed as I forgot to add a Python dep).

So basically all of the low level components are (or will soon be) in

Will keep the list updated with the progress of the wiki & zbar

On the topic of mBarcode itself, I've got the autofocus working, and you
can grab a test code here for the N900 (and a zbar deb too):

I'll (try to) debianise it this evening and also check the Diablo code
to see that it still builds after all the hacking around the N900 stuff
has needed.
