Ok, Hi Pawel then :)

I haven't looked much into the "byid" commands... but I've tried them
a couple of times, and I always got an error back. As the other
commands work just fine, I assumed the "byid" commands don't work with
this model.
Unfortunately I'm not at my box right now to give you the exact
error... I'll try again later. Anyway, getting an Id back doesn't
solve the issue of how to distinguish a regular file from a directory,
or how to avoid doing the recursion myself, at least parsing gnokii
stdout... unless I'm missing something?

Ok. I don't know how Obex work, but I'll have a look at it.

I don't know if FBUS works. Last time I checked there's no reference
to FBUS in /var/log/messages when I plug the phone, but gnokii talks
to the phone just fine.
The cable is a CA-53, but yes, I'm using the dku2 "userland" (libusb)
driver from gnokii.

On the other hand, I can transfer files from/to the phone using
bluetooth from GNOME, and I *think* that uses Obex (over bluetooth, of
course), so yes, the phone itself supports Obex.

I don't have any experience making python bindigs for C libraries.
Using gnokii directly as a module from python would be awesome; my
current approach (invoking gnokii as a subprocess, and parsing it's
stdout) is not much fun :p, but I'm not sure if I want to add another
sub-project to this project (the sub-project would be develop the
python bindings for gnokii, learning how to do it in the process); at
least for the time being this "playlist manager" is a personal itch,
and if I don't see some usable results in the short term, I know I
would lost the interest in doing it.
But then again, maybe making the bindings is as easy as anything else
in Python ;) I should investigate that a little.
