Makes me happy to see water go through bars, finally.

I have yet see it used on a modded server. Its going take work to adapt it. The navycraft oriented servers (big ships moving) going have be REALLY revamped because water works differently and additional blocks.

Vehicles move have to have blocks assigned to it so it will work or the block disappear or worse sink glitch your vehicle in to a building. :P

Yes. This is by far one of the biggest updates released in recent years. An overhaul to Minecraft's oceans is something I had been hoping for ever since I started playing.
