I had in mind storing the deltas in a log-structured database -- which I believe is what hypermerge does -- and detecting invalidity at application level and then rolling back to old log records in case of trouble -- but of course that doesn't help with losing sync, or effective loss of data from rolling back or corruption that leaves the data valid, and it's just not very practical. So, even though I suspect the problems in practice are rare (Martin's clearly a very able programmer), I guess that until he gets around to the integrity work he has in mind, it's limited to apps where the data is very transient for now. Those do exist: say, off the top of my head, a tool for collaborating on sketching simple diagrams -- in fact their pixelpusher demo is quite similar to that idea! I think he's currently focusing on performance improvements. Hope to see it grow into that!
