Can you assign user roles and/or Buddypress membership types?

I’m would like to replace the WPMU Membership on an existing site with the new Protected Content plugin but it seems some functionality is missing. I’ve found you can assign specific capabilities to specific memberships but can you assign specific roles to the memberships?

Also, I know it’s pretty new to Buddypress but are you planning on adding functionality that allows you to assign membership types? (Membership Types was added to Bp 2.2)
