Indeed ISPs don't care about port numbers (and why should they?). They
inspect packets and throttle bandwidth hoggers (this is termed packet
shaping). http://en.wikipedia.org/wiki/Traffic_shaping

I'm glad they do this because that means that most people's primary use of
the internet is not affected (email, web) by bandwidth hoggers downloading
gigs on bittorrent. As the years go by and pipes get fatter, hopefully one
day this will be a thing of the past.
