Hi Joel,

I have think one scenario where what you ask is possible.

>>...OT would only have to be applied in one or the other (presumably the
>>server)?..

Where no divergence exists between client(s) and server, like when
you have one 'Editor' and a lot of 'Readers', (broadcast concept)

We have one case on wave-vs.net where we apply Locking to document to
avoid concurrent changes, (not enforced using wave).

This scenario does not use OT as no conflict can occur at all when
there is only one people working on document.


regards

Jesus Salas
