You might want to do more than hope for portability. I suggest testing the
code under Virtual-PC directly on the Mac as a good step. You can have
more than one JRE installed on virtual Windows, or even more than one
version of Windows on different virtual HD's. And it's SO much easier to
manage than Wintel hardware, dual-boot configs, etc. It may not be as
snappy as real Wintel HW, but sometimes that's useful in testing, because
you can more easily see visual defects in a GUI.

Mac OS 10.2.1 should be your baseline OS. 10.2.0 had some significant, um,
personality difficulties.

PB 2.0.1 is markedly different than PB 1.* on 10.1. On the whole, I think
it's an improvement, but it took me some time to get used to it. PB 2 will
convert projects from PB 1's format, but doing so is irrevocable and
in-place, so do a full backup of your projects first.

I always worry about backwards compatibility of executables, especially
app-bundles. So it wouldn't hurt to keep a machine or a partition around
with 10.1.x on it, and do trial installs and test-runs of your distros on
it. Or maybe I'm just more paranoid than most.
