[support] Orienting Users around Groups

[Brian Choc]

Greetings,

I'm trying to setup a site where the defining feature for users is 
groups.  It's straightforward to use OG to assign content to groups, but 
(beyond content access) most user functions still orient around users' 
roles.  Is it possible in a reasonable manner to reduce this focus on 
the role and assign things like profile visibility and user contacting 
permissions based on groups?

Thoughts?
Brian
