Leopard "Preference Sync" with iSyn (.Mac)

Hey guys, I just got Leopard (yes, it's already out in Australia) and I love that I can now sync preference settings between my macs.

However, I had to turn it off since my iPhoto Library on my MacBook Pro and Mac Pro are in different locations and iSync always sets them to the same setting trough "Preference Sync."

Shouldn't there be an option that allows you to set which programs to exclude from this sync? As is it's pretty much useless.

Am I missing something here?
