Supporter across Multiple Domains

Please forgive me and point me to the right thread if I am missing it.

I'd like Supporter working across multiple websites in a small network.

Scenario:
- Network of 10 sites.
- Multi-Domains (premium plugin).
- Supporter (premium plugin).

Shouldn't be difficult. I just don't have the time right now.

Use Case:
1. User registers.
2. Opts to become a Supporter.
3. Based on Supporter status, User can then create up to 9 'Additional Blogs' (similar to "additional ad free blogs" as set in Super Admin > Supporter > Settings), across any of the sites connected via premium plugin: Multi-Domains.
5. When they do so, the new blogs are given the same Supporter priveleges as the originating Supporter Account.

please advise
