I followed up another message to the list with what I hope is a much more

I tend to do things where I have long-term connections, and those
connections will be reset each time the IP changes.
admitedly much of what I do is not going to be your typical school type
situation, but even things like streaming audio will break and get reset
if the IP of the box changes.
when people normally use a paptop and have it change addresses on them,
it's typically doing so at times when they would expect disruption
(useually at a time when they would close the laptop anyway)
there's a reson that DHCP tries hard to continue to use the same address.
hack a DCHP server to have it refuse all renewal requests and issue
different IP addresses each time, and you will see a bunch of problems
(set a low lease time to aggrevate the issue)
