Funny, I know of at least one company that has had a serious problem with
spam being delivered using their wireless network -- in their case, it was
particularly a problem since they had a very large pipe to the outside
world, and a sizeable parking lot.

As a home user, you can quite easily find yourself in violation of your
AUP, which can be a pain if they actually pull the plug on you.  You might
also find people using your wireless access to break into other people's
systems -- while it's unlikely you'd have any liability in that situation,
I think it would be best to discourage the FBI or local law enforcement
from turning up on my doorstep unnecessarily, especially if they're
looking for evidence relating to computers.
