Yeah and I think their cars should have regulators on them that do 
not allow them to exceed 35MPH because so many of them speed through
residential areas and the risk to pedestrains (especially children) is
so high.  Sure it is inconvienant but think of the children and pets.


If I remember correctly, and I could be wrong as @Home (or cable for
that matter) is not available at my house, their no server policy is not
for security reasons, the don't want residential customers hosting
service because they also offer a business level service.
