Well, maybe one log for tag operations, one for adding messages, etc... 
But it is easy enough to mark log entries by what they are.

Yes. This seems hard to optimize internally, but I was thinking of some
"log compression" function that comes up with a minimal equivalent set
of operations. I had in mind that this could be used to sync:
concatenate all the logs, and then compress to a minimal set of
operations.  This is still not completely thought out...
Another issue is that the buffer could get rather big during a restore,
but this is presumably fixable by flushing it if it gets too large.

All the best,

David
