Would you share your wireless network with neighbors?

I definitely say NO!
You don't know people- even when you think they do.
A family member of mine was arrested and sent to federal prison last year because he had been downloading child porn to his computer for over 10 years. He has a wife and kid and worked at a very well-respected college, did charitable work, was very granola-y, was a community helper, and was highly regarded.
You just never know people.
Everything computer related in his house was confiscated by the FBI.
His wife had no clue (encrypted files and such).

Aside from all the security issues, things like this ^ are worrisome. People have totally different internet lives sometimes. What happens on YOUR network is YOUR responsibility- even if it wasn't you doing it.

Plus, if you ever move, they will have to get their own service anyway, so they might as well just do it now.
