Expose Groups to Token and make them available to required lists

Couple of feature requests to expand interest group handling:

1. Expose Groups to Token or Fields or OG or anything really - I've poked around for a while, and it looks like groups are brought into user profiles on optional lists only for editing purposes within the profile. I can't find a way to access them using Tokens, change them using Rules, link them to Organic Groups, sync them to fields in the user profile, or basically do anything with the data. It would be incredibly helpful to my and I suspect other people's purposes if interest groups were incorporated into the information kept about users in an accessible and usable way.
2. Make interest group selection available on required lists - Each list type has wildly differing capabilities. It's very confusing that interest groups would be inherently unsuited to fully synchronised profiles, but I could be missing something obvious. At any rate, what I'm trying to do is create a single sign-up form for the front page of the site, and required list is a useful way of reducing the number of sign-up items and complexity of managing bridged accounts across Mailchimp and Drupal.

May be willing to pay a bounty on these if anyone is thinking of doing these in the near future.
