I have created a multi-network system to separate separate network/buddypress installations, giving a little more customization options per buddypress install while sharing a user base and marketpress base.
So far all of your plugins have worked great with this new system except Multisite Theme Manager.
I am getting a permissions issue saying that I do not have admin privileges to edit. It is not showing up on the settings page. When I follow the link that shows up on the theme page an error message says “You do not have sufficient permissions to access this page.”
