[Mesh] mesh at first friday?

Hi All, I heard talk about running a mesh network at first friday, and mark said y'all were planning to make it happen. He showed me the POE injector and I offered to make some harnesses to go between a few small 3.5Ah UPS type batteries and the barrel jack (center positive?) that plugs into the injector. Are y'all still thinking of doing this? I would like to contribute to the effort however I can - there are 4x 3.5Ah lead acid batteries and one larger deep cycle battery and I have 2 dinky wall chargers to top them off. If 3.5Ah is not enough, I'll make the harnesses to use 2 batteries in parallel. Anyway, I've been meaning to help out but haven't felt I know enough about networking to contribute meaningfully, so if this type of low level hardware would be of use for first friday I'll build tonight and bring to tomorrow's hack night for testing. Cheers, Hol
