each requested db row becomes a deepstream record. every user connects to the deepstream server, and only the node.js script connects deepstream to whatever database you choose to use using sequelize.
my next step will be to let users create and name their own unique queries, so if two users have the same query name, they will be sharing the same deepstream set of records. and if two separate user queries just happen to share the same deepstream record(s), this will work fine too.
my goal is to have two different ways to accomplish the same goal: the start of an sql framework. the other approach is to find somebody who is willing to write a feathers.js-sequelize tutorial in exchange for a flying toy and share it publicly (share the tutorial, not the flying toy).
