CommunityEngine

Sorry, still need your advice. The social network I'm building has a bit more complexity, so wondering if Community Engine is a good starting point. 

I will need 3 different user account types, and the 3 account types will have different features set (eg. one account type will not have access to the blogging feature, another account type will have custom built features, still another account type will not have a public profile and will not be searchable, etc).

For example, maybe a social network for schools will have teacher accounts, student accounts, and parent accounts. Perhaps teachers and students will have public profiles, while parents may not (their account would just be to track students and grades or something). Teachers may have a blogging feature, while students and parents may never need to blog at all. (just using this example because i saw teacherly.com) While we're at it...would it easily be extensible to include "groups", the obvious application here being users joining schools, teachers associations, school clubs, etc. 

Will Community Engine plugin support this level of customization and extendability? ... and will it make a good starting point for a non-standard social network where everyone is basically treated the same in terms of features-set?

Thanks...I'm thinking this is a question for Bruno!
