PouchDB uses the CouchDB sync protocol to sync to multiple servers (or other PouchDB databases). PouchDB is also planning on offering a lightweight server-side PouchDB that runs in Node.

FWIW any database could potentially implement the CouchDB sync protocol. http://dataprotocols.org/couchdb-replication/

There actually is a PouchDB Node server already: https://github.com/pouchdb/pouchdb-server/. Installing it is as easy as `npm install -g pouchdb-server`

Also, Drupal recently announced that they're going to offer a CouchDB-compatible server. So yeah, anybody can implement the sync protocol. :) http://wearepropeople.com/blog/a-content-staging-solution-fo...

Thanks! How did I miss this?

Thanks! This would definitely make it vastly more popular!
