Yo, it's very much a work in progress and yet the main goal was not
loose any functionality by getting rid of the externals. I did not
address any bugs yet, because I didn't experience any.

I only have a arduino Diecimila to test here. So, I ask you again: The
problem you mentioned with pin 2 and 3, on which arduino board model do
you experience it? Also, if the problem is located in the firmware and
not in the [arduino] abstraction, I rather don't 'fix' it in the
[arduino] abstraction.

Since you seem to have a strong interest on making it work for your
situation, I suggest to give you commit privileges to that repository.
You could send me your public key off-list and I would give you access
to that repository.

Also, thanks for your other comments. Those are all valid points that
need to be addressed.

(Actually, 'pduino rewrite' as thread was a bit too much a promise, it
should have read 'please test and report back'.)
