Until Technic is SMP compatible though (and I hope that day comes soon that I can Chernobyl the server) I think it wouldn't hurt to give Buildcraft a try. If we keep the current map then we can always come back to it after a time and it'll be fresh again.
We'll need to put plenty of links about on the front page and that to make sure peeps download it right. It's pretty easy to do, even has its own little custom installer.
I just have to figure out what all the stuff does
I think I'll be watching a few videos later.
