Anyone got portal and want to try and get multilayer working?

I was reading though a console command page (http://uk.gamespot.com/pc/action/portal/hints.html) and I saw something that caught my eye, I only really want to do this with people I trust as I will have to give you my IP.

EDIT: got it working but portals are buggy, least we can see each other. Now to fix portals :'(

You can trust me, for sure.
