Echo JS 0.11.0

I am in search of ORM library for Meteor (http://meteor.com) (MongoDB in server and minimongo in client).

My requirements are all features must work seamlessly on server and client side.

Q: Which features do you think are lacking in the current JS ORMs?
A: - Validation
   - Associations

Q: What are the most important design goals / features / characteristics you look for in an ORM? (performance? user friendliness? level of abstraction? good documentation? etc.)
A: - Work seamlessly on server and client
   - Documentation

Q: Are you interested in contributing? Hit me up on Freenode (my nickname is olalonde).
A: Yes, of course. I try to implement Meteor's ORM on myself but failed.

Q: If you had the time to go through the README/tests in the Github repository, what are your thoughts so far?
A: Somethings:
- naming conversion: if you planning to Browser compatibility, you should not prefix method with $.
- validation: implement node-validator
