Tiki should be become a tool to build multi-sided platforms

The organization that creates value primarily by enabling direct interactions between two (or more) distinct types of affiliated customers is called a multi-sided platform (MSP)

This goes beyond a Shopping Cart. It's about connecting people, organization and projects. This feature should be like a Shopping Cart but where anyone can put items for sale. Think classified ads, car pool, etc. Please also see: http://en.wikipedia.org/wiki/Rental_management_software
