Traditional Chinese Big 5 HKSCS works with syncs between a PalmOS 5.2 Clie and Addressbook, iCal via iSync, as well as with the standard conduits for Palm Desktop 4.2.1. The developer is extremely helpful and responsive in resolving a minor installation issue, which in turn was probably due to a workaround for the buggy Palm Desktop installer. Remaining missing custom fields problem lies with iSync's poor Palm conduit implementation. I would have preferred a true shareware approach, or at least a fully functional trial period, but the price is low enough to warrant a bet which turned out fruitful.
