I am currently a beta-tester for shopplugin.net. I think this is going to be a great solution. I’ve done some preliminary testing with it on wpmu(no testing with bp) and it worked for the most part, except it installed db tables as global instead of using blog prefix. But that should be an easy fix. I would highly recommend looking at it as I believe it to be well written software and have been impressed with the developer behind it (I have no relation to him). One thing though, it’s not free- it costs about $55
