I would like to participate in #1 or #2, but it's not obvious to me how I could help. I live in the warehouse district of downtown Minneapolis on the first floor of a 4 story apartment building surrounded by other 4+ story buildings. My line of sight out the windows is limited to 50 meters currently and will be reduced to less than 10 meters when the building next door is finished. My guess is that this precludes me from providing any kind of public access point or possibly even accessing someone else's. Is my guess correct? On the bright side, there is currently a 20-30 meter tall construction crane right outside my window. I could covertly place an antennae on top of that. ;> Mike Bresnahan
