OK, so the important point here is that while you probably delay events for a small amount of time (1-3 seconds maybe) to ensure that you aren't processing steps out of order, it's not likely that userspace is going hold event #1321 for an indefinite period of time just because it has never seen event #1320.
I can't wait to see this implementation; it's going to be interesting, to say the least. However, without the sequence numbers, it would very likely be impossible.
