Californian Assemblyman Mark Leno (D-San Francisco) has announced he will be introducing a Net Neutrality bill. Supposedly that would prevent ISPs such as AT&T from charging higher fees for certain kinds of data traffic from selected content providers.

I’ve been a proponent of Net Neutrality but I really wonder how this would work technically if Calfornia was the only jurisdiction where Net Neutrality was the law.  Since data flows from everywhere to everywhere, what legal constraints  can be placed on the owners of the big pipes that only pertain to the geogrphical boundaries of one state? Perhaps a network engineer could clarify this for me.
