Is there any way to generate QR codes on badges?

Ideally: I'd like RegOnline to take a url format like "http://my.site.org/%id%" where %id% would be replaced by the registrant's ID, for example, and then insert the corresponding QR code onto the badge.  Maybe it would even auto-provision a bit.ly URL or something.

That would be fantastic.

Any chance for a November conference?

Does your system have a plug-in API of some sort so I could do it myself?
