I've been reading the FON web site, http://www.fon.com/en/info/whatsFon
, but I haven't really done enough searching to have most of my questions answered.
However, as I interpret it, users who want free WI FI through FON agree to share their home broadband network with other FON members ("Foneros"). FON provides a router ("La Fonera") which seems to incorporate security features, though I didn't find them explained. For those who don't share their home WIFI, they can still join FON and buy WIFI when they are on the move.
This sounds like a wonderful idea, though how it would work for cruisers without a land base to return the favors I'm not sure. But since there is a way to buy WIFI connections, cruisers should benefit with the proliferation of WIFI spots globally. I wonder if advertising revenue is also a way that this operation makes money.
Something to watch. Thank you, Peter, for bringing this to our attention.
