Palm wireless networking via IrDA (MacOSX Hints) – I use the following AppleScript to share my broadband internet connection with my USB-attached irDA adapter. This allows my Palm to use my network connection so I can sync AvantGo (modem sync) and download emails directly. [Mac Net Journal]
Very close to getting this to work… seems a bit tricky actually, but worth it if, I can finally let me sync some of my network apps at work (no wifi yet).
