Keith,
as one thinks about VPNs, tunneling, mobility and the like, assuming a week is
probably a bad idea.
Think a bit about the way AOL's IM tracks the binding of an IM handle to an IP
address - it is quite dynamic.

IMHO, apps should be able to assume that an advertised address-host
binding is valid for a minimum of a week. This is a minimum - it
should be longer whenever possible. (however there's no requirement to
maintain addresses longer than the nets will be accessible anyway -
i.e., you don't expect the addresses for the ietf conference net to
remain valid after the net is unplugged...but they shouldn't be reused
within a week either.)
