Say you were thinking about building little noise modules to sell for a couple bucks each.
Further, say that you don't yet have a website and though you do in time intend to, at the moment you don't really have the knowhow/time to set up a site with it's own shopping basket.
Where would you host them?
Is there a BandCamp/Soundcloud for software?
I just found a wordpress plugin called Dippsy - http://dippsy.cz.cc/?page_id=57. Looks like just the ticket.
