While everyone seems to be talking about people abusing your open
networks to download child porn, there is another issue: on an open
network, not only can everyone connect - any user can also snoop on,
and/or inject fake data into, any other user's communication.
The solution could be creating a modified version of WPA that does
encryption, but not authentication (i.e. lets anyone join the network,
but prevents one user from snooping on another one).
