I'll leap in here too...

If Windoze is smart enough to autodial when some program wants to use the
internet it then should be smart enough to notice that the connection has
gone idle and do an idle time-out for hanging up. If not, then its broken.

You can't blame the program that USES that auto-dialed connection for not
hanging up. It didn't dial, why should it hang up? Every program that might
use the internet (auto-dialled) now has to be modified to know how to hang
up the connection? What if you have two programs using the connection at
the same time, and one of them decides to hang it up? Oops. Clearly not the
right solution.
