Ah. Seems reasonable. You could probably tweak the timing (updates no more often than every X minutes) and volume (no more than Y changes per update) dynamically with things like an exponential backoff (to some limit) to optimize engagement over time.

The ideal knob settings may change depending on whether people are trying to collaborate synchronously or asynchronously. BTW, are you currently doing diff-match-patch to account for multiple editors?
