This has been discussed before, and the problem is quite complex. The
main problem is that it needs to be specific to a particular network
interface. To use your example, you don't want an imap connection to a
server on your lan to be terminated if you close a PPP link to your ISP.
The situation is even more complex for machines with several network
cards (or multiple addresses using IP aliases).
