I also would be grateful for an integration with Jomsocial. I can provide you with the component.
What I need is for users of the community to have their own media collections. I don't need back end submitting att all, only front end user submitting with the amazon cover art feature.
If making a user collection part of Jomsocial is too much, maybe a frond end submit function with a Jomsocial plugin that displays the users submits in his/her profile would be sufficient.
To also integrate this with Alpha user points in such a way that users can request products from each others collections/listings and retrieve/spend points would be really nice as well.
Here is the developer documentation for Alpa user points:

I'm a poor student, but I could pay if you can provide a custom solution to this.
Regards,
Isak
