IMO, this is dead on.

We group your first two requests together as a project called Routes, and it will be one of the big initiatives we take on once the authorization and account work is shipped to production.

As for your third request, we're been careful with this. Internally, Meteor is already database agnostic. For example, DDP, the Meteor wire protocol, is based on tables, and all of the code that performs latency compensation, etc, doesn't make any database assumptions. Mongo support is provided by a Smart Package that includes the client-side Mongo emulator and the server-side Mongo connector. Supporting SQL, Redis, Couch, etc, is a "simple matter of programming." We'll likely do Routes first since there's more technical risk there.
