The PIX isn't 'broken'.  It was fixed some time ago.  It's just that
some folks don't want to take the time to upgrde their devices.

This same issue applies to older releases of LocalDirector code, as
well.  Again, Cisco fixed the problem with alacrity; again, some folks
just don't perform timely upgrades.
