A micro-economy for the Addons site?

As an extension developer, I'd very much like to see the ability for an economy to develop around the Add-ons site (even for sandbox items). As a number of sites are doing now, open source projects allow paid services to be associated with a project (the opportunity to take donations, for users to make paid offers to the pool or an individual). I'd also especially like to see the ability for a developer to offer to develop something or work on something if pledges for a certain amount can be given.

I think the great success in participation that Firefox Addons have garnered could be amplified if participation could be extended to would-be small-scale patrons who'd like to see interesting features implemented and made available, or to corporate or other sources of funding who come across a trusted developer and good idea which they'd like to see implemented, or make their own request for a particular tool.
