When a Palm beams data using the Exchange Manager, it does a single PUT operation. The
instigator is also the sender. The Exchange Manager does not currently support doing a
CONNECT followed by data flowing in both directions. It doesn't even support doing a
GET, where the instigator only receives data. We recognize that this limitation is a
concern for our developers.

Check out IR Ping. I'm not sure where it is, but check road coders, PalmGear, etc.
I needed to do two-way IR communication in BeamBooks, so I wrote a layer on top of the
IR Library to provide a UI and API along the lines of the Exchange Manager. I made no
attempt to make it OBEX compliant since I was communicating with another device
running BeamBooks.
Perhaps IrCOMM would work for you. You give up control over how the connection is
made, but you have a 2-way streaming interface once it's up. Or you can do what I did
for BeamBooks and use your own protocol on top of TinyTP on both the Palm and the
embedded device.
