Lol, I am on the road all day, i fix heat and a/c, and my 3g sucks around albany so when I am on lunch I lurk around side streets looking for open wifi. Luckily for me most people are unsecure.
My thread I can side track it.
If every one would leave their wifi on we would all benefit greatly. Its just a hard sell in our culture. People are not very open to others using something they pay for. Yeah there would be leaches but there is in every part of life. Best way to deal with them is shame from the herd.
We could start taking advantage of things like on the fly connection switching. In urban areas where most of us live you could use your wifi walking down the street or even riding the bus.
Some where I have a link to where a guy is working on an app to do this. The connection doesn't switch as soon as a new connection is found it waits for a point were the current connection drops bellow a trigger or the new connection is stronger than the current before it starts diverting your traffic. Its also caching a separate buffer of network data necessary to speed up logins.
Also I don't feel bad cruising open wifi. The providers all warn you when you have internet turned on about the "security" risk of open wifi. Its common knowledge that its open and any one can lock on.
My family is one big traveling hotspot. I leave mine open and the rest of my family hate dealing with the password so are open out of laziness.
My wife laughs about how she always forgets to turn foxfi off and she will be on the interstate going to work and her phone will foxfi chirp when ever shes near a semi.
