An open source order management system is interesting to a certain number of people, but probably doesn't affect me personally. It sounds like another open web storefront builder if i had to guess based on the title.
An open source Amazon is a big deal, it implies that it aims to do what Amazon does, not just a repo you can clone and build an online store, and I might be placing orders there someday.
A distributed open source Amazon. Storing goods in people's rooms. Creating a distributed worldwide warehouse, kinda like P2P. With a fleet of uber-like delivery persons. Each participant gets a share of the profits.
