Should I Cc them with droid 4 emails? I assume they are on
maemo-leste@ list?

So... yes, that really should happen in parallel.

Now, I see you want to be similar to Maemo (and it makes some sense)
but I'd really like to see different design, one that treats SMSes as
emails (not like instant messages), so I could read them using mutt and
use imap protocol to access them remotely. I'd like to store my
contacts in plain text (version controlled in git), not in binary
databases.

But that does not mean Telephathy stack can't run in parallel...

I see proper integration is tricky; but it is not strictly neccessary
for now. Unicsy demo is ... basically meant for testing. It should be
good enough to test phone functionality and battery life, but for full
integration we want something else.

I have created a release 0.5.1:
https://github.com/pavelmachek/unicsy_demo/releases/tag/0.5.1

Current ofono is subtly broken, and will not work at all with latest
kernels.

Ok, good.

I'm not sure how Maemo side is supposed to work; so I'll just do it
"by hand" for now. I need to turn mixers into "loud" mode for ringing,
then "in-call" mode for actual call, then probably back to loud for
standby...

Ok.

Ok.

I believe we are very close to getting them to behave. Cross your
fingers for me :-).

Yes, normal earspeaker works for me (kernel
127a82e23c23c6d1ef93bd978b99ce8cc0030b97; I may push it somewhere but
it contains >100 unrelated patches). I never tested headphones. Audio
code was rewritten in the meantime,

Exciting parts are over, now it should become boring :-).
