Who do you think is going to do this reflashing? If you think that Grandma
is going to download an image and reflash her linksys, you're at least
slightly divorced from reality.

If you think she's going to do it and not have about a 10% brick rate
(10% of devices going from router to brick) as a result, then, you're
optimistic to say the least.

Which is why we should decide to move to IPv6 and get on with it instead
of continuing to pursue rat-holes like 240/4.
