Like Danny, I wrote an obex-like layer on top of the pilot IrDA stack.
Here's the ir_ping reference:
http://www.ibr.cs.tu-bs.de/~harbaum/pilot/ir_ping.html
Next, you may want to try Glenn Bachmann's "Palm Programming"
book. ISBN 0-672-31493-2
Between these two I had enough information to get a low level (TinyTP)
IrDA link between my Linux Box and my Pilot.
