Agreed, it is interesting. But no, I don't think it is worth it. > Have you measured the jitter? Yes. It wasn't huge on a LAN, from memory about 2ms at 10 Hz.

Yes, it would make them stale, but making all packets stale by a small amount would be acceptable. > Dropping a packet when it couldn't be sent in time doesn't sound very > appealing either. Indeed.
