Open World - Howard Street Tent, in the OTN lounge.
If you want to build a 2 node RAC on your laptop (which has 4GB RAM, Windows, 50GB disk) or you want to set one up on the Pythian laptops, come over.
I've been here this morning, helping out.
I'll be here from 10:15-11:30 tomorrow as well.
You can also install it on your own, with the core instructions from http://racattack.org
