Just found this thread. Not sure what I'm doing that weekend, but given that I live in the area, put me down as tentatively attending. As far as boards go I don't have much, but I can bring a Dolch PAC 65 keyboard (and hopefully the mod I'm planning to get it working over USB will be ready by then). Hi-Fi - I have a Sennheiser PC360 headset, I think that counts (it's basically the 595's with a mic attached). Could also bring the WASD V1 in my sig if someone is interested.
Edit: I forgot to mention the cherry G84-4100 I have on order - will also bring that, too. ML switches!
