The fixed point is the LuckyLab. Using an omni with no amp, the mobile AP can be placed within an estimated 4 blocks of the lab. So somewhere in the four block radius there must be a point with line of sight to the 'home' basestation. The thought is that FreeGeek will be home base.
ChristianSeppa writes that he has a connection to the owner of a warehouse kitty-korner from the LuckyLab and will attempt to use all non-coercive means to get an AP set up at said warehouse. Updates will be posted as events develop. --ChristianSeppa
