Question re Restricted Area module

I am using Restricted Area to restrict to a group of areas which are essentially items sold through Simple Commerce.

For example, there are 5 items for sale and thus 5 restricted areas…obviously when someone purchase Item 1 we have to manually assign them to a corresponding “Area for Item 1” so only they have access to it (be good if this could be automated like the SC puts the purchaser in a specific group the same could be done to put purchaser in Restricted Area - but it is beyond me and that’s not what I’m asking!!).

My question is this: How can we have the purchaser see what they have purchased on their profile page, say, defined not by Member Group or Purchased items (I know this can be achieved by a Query) but by their membership of Restricted Areas? It has to be this way because the Restricted Areas is set up to mimic multiple group membership and the Purchased Items route won’t work because people can buy without being logged in or other people can buy for them..

Is it possible?
