WOW! This is super cool news man! Thanks Seth for your efforts! Let's make
it happening :)
I am guessing we will need to have an internet connection on the server.
There going to be Conference WiFi in the area. We need to ensure that the
server we are going to use is hooked to the net (I am not sure if wired net
connection is going to be available onsite). Therefore we may want to plan
to use one of the Laptops as a proxy server.
