How do we decide what the smallest unit is? For text collaboration should it be a word, a paragraph?
Is there going to be performance issues if the unit is too small? But it might be more flexible

A:
Implementing the multi-user interactive editing capabilities of Google Wave probably requires a unique data structure, not something that fits into a conventional relational database.
It all depends on your needs, of course. Do you want to recover the full history of a document? Or the order in which a user typed it? How many users? How many documents? All of these things will impact the data model.

Depends on what your goals are.
A "message" (one user to another) seems like a good unit.
You'd attach other stuff to that message, of course, like timestamp, session id, to-user, from-user -- whatever is necessary to reconstruct what actually happened.
