Can PB be used in the following way.

-site is an wpmu one with multiple blogs
-users register on main site
-bp activated on multiple (not all) blogs in the network
-once logged into any bp activated site, users can use bp functions on that site

-however, would like to have profiles only on main site
-would like to allow blogs to display various bp users functions such as members and other things

This is the most basic of use I am looking for. Is this possible and if so, which plugins would I need to activate on each blog?

Thank you.
