I have put a file fakehid.txt in the CVS with the characteristics of
this keyboard and also the presenter device.

Make sure to send me one for testing ;)

The Nokia 770 has no supported HID support. However you can install an
applet that gives you keyboard support. This however runs hidd and so it
should not be a big problem to integrate it.

The hidd needs D-Bus support and a small redesign. However at the moment
we are just finishing the D-Bus support in hcid and its sdpd integration
and so it might take some time before we start looking at hidd. However
feel free to propose something.

No idea what this means. Nobody needs a secure mail server to subscribe
to bluez-devel. Simply use the webform to subscribe.

It needs a little bit nicer and cleaner integration work, but it seem a
good step forward to make this keyboard work under Linux.
