Supporter Affiliate + Buddypress Invite Anyone plugin

I realize part of this question has to do with a free buddypress plugin, but perhaps someone has thought about this and come up with a solution. wp 3.0.1, bp 2.6.1.

with buddypress, i am using the Invite Anyone plugin. i am wondering if there's a way to automatically add a given user's Supporter Affiliate link to the invitation email they send their friends through the Invite Anyone plugin's interface. that would encourage more people to send invites. of course, if i enable the user the ability to edit the message, they could manually put their affiliate link in there, but it would be nice if this was automated.

somehow, add some code to Invite Anyone, that checks if the user is an Affiliate, if so, then add their affiliate link into the message.

any ideas is much appreciated.
