I really like this idea, and am well happy to put up hosting and coding time to build it.
In terms of splitting commercial and open source, how about you just add a Paypal IPN system, where the developer puts there paypal details in and the system enables a Buy Now link.
Not sure if you could charge the developer a one off fee or a % of sales or nothing (though bandwidth does cost
)
To move this forward why not PM me, and we can then setup a Basecamp group and work off tonanbarbarians model?
