starcraft multiplayer lan 2 macs

i've searched and searched and searched all over the internet, but can't seem to find out how to play starcraft multiplayer on lan between two macs.
i have a macbook and ibook in the same house with a wireless network. it works fine with pc's, but we cannot see each others games. i tried connected the two computers with a strait rj45, to no avail.
we were successful with this once, when playing with a third computer (PC) that created the game using "direct connect" with the two macs using the udp network.
any help?

Maybe you could trie this:
HamachiX - The Mac OS X frontend for hamachi

I'm not familiar with the mac version, but for pc was a really good app.

i love this thing for pc, but i have tried the mac version to no success at all.
though, all hamachi does is create a fake lan over the internet. i'm on a real lan.
thanks though.
