Gift Registry - Willing to Pay or Donate

OpenCart seems to be the only popular cart that doesn't have a well-established gift registry module. These are common on retailer's ecom sites. I have searched the forums and can find other mentions indicating market demand, and a post in the roadmap thread, but haven't found any real progress.

Does any one have any leads? I'm willing to buy a commercial extension, pay for development, or even sponsor the development of something to contribute to the main opencart. (note: Client is running 1.5.1.3)

To be clear about what I'm asking:

• Registered user can create a gift registry for a given event + add products to it, as well as send email invites to the registry (via encoded URL)
• Friends of registry owner can look up the registry and buy products off of it (as if its a checklist) to gift to the registry owner.
• Registry owner + any friends can see status of registry in real time

The 3DCart documentation essentially serves as a spec for a workable gift registry that can be easily adapted to OpenCart. An adapted version of this would be ideal, and would also likely help the OpenCart community as the lack of a good registry module is undoubtedly impacting the popularity/adoption of OC.
