The latest build, 2.50 is running great! On Leopard that is, I can't get it to work for Tiger anymore.
If you have a license for MacDust and are still running Tiger, please send me an email, I would like to know how many people this is going to throw off. I'll do my best to try to get Tiger compatibility, but I'm only one person.

Update: Thanks to Ed, I was alerted of a Leopard compatibility issue with the Maintenance Scripts. Half an hour later, I have a patch!
