One round-trip at the cost of more code on your side.

Right, except that for sound we have a "broker" application in PulseAudio. There's no such thing for V4L devices. In any case, it should probably be a separate application that would take the data from bluetoothd and make it available as a video device through v4l. The VDP-using webcam I have uses MPEG-4 as the video codec, and you probably don't want to have to reimplement that, so the broker app could probably use GStreamer to make the video available. > > I'd be happy to do testing and some integration work for both the VDP > > and DUN works. > > > > I could also add: > > - Port gnome-user-share to obexd, instead of obex-data-server (easy) > > - Port osso-gwobex test suite and extend it (medium) > > (Those 2 could be combined into one project) > > - Printer (initial) setup integration in gnome-bluetooth (medium) > > I guess those are too gnome related for being in BlueZ, expect maybe > gwobex, of course we could help/co/mentor projects under gnome > organization. Or vice-versa :) Given that porting gnome-user-share to obexd shouldn't be a long winded task, porting the osso-gwobex test suite would nicely complete it. The printer integration work could probably be re-used by other bluetoothd-setup front-ends like KDE. > > - Extended hostname support (using xdg-hostname) (medium) > > - Kernel driver and user-space changes for Sixaxis joypad (including > > rumble).
