There was some discussion here

but we never really got around to implementing anything. Personally, I
fell that I lack the overview of the different pda devices to build an
abstraction around it. 

My gut feeling is that most USB-based pda's just have a USB serial
adapter stuck onto them and in that case it would suffice with just
tagging that USB device as 'pda' through device information files. I
could be wrong though. 

There's also the question of making the desktop use the information we
expose, e.g. for GNOME you would have gnome-pilot listening to hal and
do it's thing when hal says "Here's a pda".

For Bluetooth pda's, I don't know. I think the approach to take there is
pretty much covered by bluez and the various desktop Bluetooth stacks -
Bluetooth is pretty much the same as networking and I'm pretty sure hal
shouldn't be involved at that level (just like hal isn't involved in
actually managing your network connections - NetworkManager is one
example of that).
