That's the problem isn't it? Who decides what can and cant go through. I think the tier approach is better, a basic 
user account where everything is blocked and a Sysadmin type account where everything is open. If the price is 
different enough then only people who are going to use those extra ports will actually pay for it.

To me there is no question of whether or not you filter traffic for

SBC in my area (Dallas) went from wide open to outbound 25 blocked by
default/opened on request. I think doing the same thing with port 22 would
hardly be an undue burden on users, and would help keep botnets in check.

Might as well do TCP 20, 21 and 23, too.  Woah, that slope's getting slippery!
