From a List of Plugins that are all WP3/BP Multi-site compatible -Are there any that are known to co

I have successfully installed the multi-site fuctionality to WP3/BP (with lots of help from many of you). Now I am in the process of adding plugins. Mine will be a humor site where friends can exchange blogs, stories, photos, video, etc. and communicate with each other. We will also have a few ads to support local small businesses. The site will have both "members" and visitors.

My question is; Are there any plugins that conflict with each other although they are individually compatible with WP3/BP Mutli-site?
