Searching for Scale

Notes to self:

Are there applications for the Mohring Effect at the packet levels of web applications? eBay made money on this model and created a monster market. I see a nice billion dollar market, increasing demand but increasing COGS as well.How do I drive down price at a constant COGS level with additional services added and hence able to serve more? How?Apparently I never graduated from school since I dont know the solution.
