http://www.minecraftforum.net/topic...now-with-vertical-wind-mills-v434-upd-nov-12/ This mod would be really helpful for interesting builds.
Too much work, lag, people not used to it, abuse of the new items (spamming them all over the place like beacons), and really this isn't needed at all. In fact it would probably make the server worse.
Honestly I would not want this mod on the server. I like it the way it is. Personally I think the only mod that needs to be on the server is Camera Studio Mod + all the anti griefing mods and such
