For those of us with completely random, or not, interests in Internet and WiFi I was cleaning/organizing my Favorites folder and found this link. It is of some value to whom I'm not sure but wth eh? World Wide WiFi Locator
I just played with it a bit and there are surprising number of San Pedro/AmbCaye wireless systems already in the map. I'll be putting ours on the map once I get the specifics of the system.
