Equipment -- don't think so, unless you want to buy a few BYOC slots to show off your rig :) (hey, actually that's not a bad idea if you're in the northeast)
But presence and expertise, well I'll leave that up to you. My goal is to have Artemis installed on some of our "PC Freeplay" machines for attendees to play, but my challenge is that it appears to have a bit of a learning curve. Can you ping me at my gmail.com
account, username "taumeson"? Basically I would like to understand more if this is something that a casual attendee would be able to get into during the course of an hour or so, get some exposure, and maybe generate a little bit of interest.
