FWIW, the SNIFFIR utility included in the Win2000 DDK is pretty good.
It passively observes IrDA communication between two devices.

Are you by any chance using Linux? If so, you may wish to install the
latest irda utils (and kernel...). There's a utility called irdadump,
which is irda packet sniffer. I've used it extensively to see what going
on. I'm not sure if it can be configured to passively sniff - in other
words, the irda modules running in the Linux kernel actively seek all
devices in the IR space. This would probably disrupt your pilot to pilot
communications.
Here's an irdadump log of the linux box downloading a .prc to the pilot:

I'm not an IrDA expert either and so can't provide a meaningful
interpretation. However, the abbreviations in the dump are the same
you'll
find in the IrDA specs.
Hope this helps,
