We are in the same need right now. Something that we have researched and think it has a lot of potential, at least for us is James Long sync implementation. You can check out his talks and demos at: * https://www.youtube.com/watch?v=2dh_gtndayY&feature=emb_imp_woyt https://www.youtube.com/watch?v=2dh_gtndayY&feature=emb_imp_... * https://www.youtube.com/watch?v=DEcwa68f-jY https://www.youtube.com/watch?v=DEcwa68f-jY And his demo implementation (and annotated fork): * https://github.com/jlongster/crdt-example-app https://github.com/jlongster/crdt-example-app * htps://github.com/clintharris/crdt-example-app_annotated/blob/master/NOTES.md I wonder why there isn't some open source engine based on this at least for CRUD apps since it has a lot of potential and it is really "simple" to implement and even understand.
