Most isps seem to have no problems with the Well Known ports being open
inbound (unless they are explicitly banning servers, including p2p and
game servers). To have to individually control open and closed ports for
dialup, cable or dsl users would be a major nightmare - not to mention a
massively customerbase-reducing move.

Proof by induction? a huge number of people have travelled far enough
from home that "noon" is noticably offset from home time, and called
home by telephone.
