Buy Contents event

I've asked this question before with out a lot of response and I've come to the conclusion it's not possible but I wanted to post again and see if anyone had any ideas.

So I have this service (http://www.SLSalesTracker.com) which does in world sales tracking and business analysis for people who use it. Often persons ask me if they would be able to use the built in “buy” type of selling with my service and I have to tell them no because I do not get any events when someone “buys contents” from a single prim.

So the question is, has anyone been able to figure out a way around this? Is there a way I can run some scripting when someone buys the contents of a prim? If no, is there a place I can request this functionality from the people who make this world possible?

Thanks for any advice anyone can offer. I appreciate it much.

If the content objects were set to no copy, would the buy give the contents and remove it from inventory, generating a change event?
