I have been known for instigating, so here it goes...

What happened to the golden security rule of "Deny everything, except what is truley needed."  I
mean most ISP's User Agreements state that you are not allowed to run web servers, email servers
and etc.  Therefore, only port a few ports ike TCP 80, 445 and perhaps one or two more are really

The second thought is, what if ISPs were like cable companies.  What if they only allowed specific
ports (like channels) that they seem appropriate to their users???
