While there is already code which enables synchronization
of a PalmOS device over Bluetooth using DUN (dial-up
networking), that seems unnecessarily heavyweight and
harder to secure than the other approach, synchronizing
over an RFCOMM "virtual serial port".

Enclosed please find a patch to rfcomm_sppd which adds
"server mode" code.  I have gone back and forth on whether
server mode should contain a loop around the existing
single-transaction code, but figured I'd send in what I
have now and let the maintainer make the policy decision.

I don't have an obvious way to test the (original) client-side
RFCOMM behavior, so it would probably be a good idea to make
sure I haven't broken that, though I tried not to.  Also, feel
free to let me know if this approach seems wrong in some way.
See directions at http://howto.pilot-link.org/bluesync/ and
ask yourself if it wouldn't be better to skip all the dialup
networking setup on both the Palm device and the host--and
also close that worrisome "-p net:any" door.
