Hi mikejk,
Although Garageband supports standard AU instruments, the instruments that ship with it (and those included in the Jam Packs) are proprietry - they will work only with Garageband, Logic Express, and the more recent versions of Logic Pro. In that respect, the Apple applications represent a rather "closed" system. However, there are many excellent third party instruments available that will run in Metro. The best news is that Metro allows you to run both VSTi and AU instruments!
That said, you can run Garageband and Metro at the same time, routing midi from Metro into Garageband through an IAC bus. Make sure you're running a fast Mac though, Garageband is very CPU intensive. Good luck!
Mike
