Would our admins be inclined to write a plugin to help with boat lag? I'm talking about the problem where, after you've been in a boat for a while, the server and client no longer agree on where your boat is, so you end up hitting things 100 blocks away, or when you get out of your boat you can see it off in the distance, but if you swim over there you can't punch it because it's not really there.
I was thinking that if there was a command that teleported you to your current location, then if teleporting actually moves your boat with you, then that would help.
