Vector gates are already there.

In lua/autorun/wiregates.lua. This should enable them for use (but I've not tested it yet):

Just thought I'd let you all know.

EDIT: posts! Woohoo!

BP said vector gates work, but wire wasn't designed to use them. They are kinda hacked into wire, and the devs felt it better to just keep them disabled until wire 2.

Awwwww.

Anyway, I tested a few and they all seem to work fine. It's a shame to not use it so can't you just add it, pretty please?

There's gates? So we could have been using these the entire time! Heh, ill activate them on my server just to confuse people. Nice find Azrael.
