Wildcard associations

I've begun developing a very basic rules integration for this module. I should be able to have it functional within the month. It currently functions but with many "what-if's" that need to be sorted out - however, it is a very simple .rules.inc file to add rules functionality to this module. Currently, it creates an action that adds a directory for a given user to the list. It will be expanded to add roles as well. Additionally, I'm looking at deleting a directory from the list using a similar rules action.

While this will provide an incredibly larger use-case for this module, it seems that creating rules in this manner pokes at a structural issue with the module as a whole. The functions that write data to the database for the existing module are heavily integrated into the modules forms. This means the rules inclusion has to recreate this functionality rather than simple call to extant functions that do exactly the same thing. If anything in the module changes, the rules module would have to have the same changes.

Would you be open to pulling the portion that writes to the database and deletes from the database out and making them their own functions which the form passes the data to? (And therefore rules would be able to pass the data to as well). I'd be willing to volunteer my time to assisting in making this happen as I feel this module is very valuable for the Drupal community as a whole (once people realize its implications).
