I don't imagine that there would be much legal backlash as long as "legitimate" users were supplied with an upgrade, especially if that upgrade were provided before the remaining devices were made to fail. Note that this seems to be exactly what is happening with some receivers that predate the broadcast flag mandate (you remember, the receivers that the FCC and broadcast flag apologists claimed would continue to work unchanged after the flag was enabled) so there is precedent. See for example:

Now of course, there are cost tradeoffs between plugging a hole and placating the "legitimate" owners of the equipment you need to upgrade. Given that the original broadcast flag proposal was pretty much a rehash of existing digital rights management proposals for other consumer content (and the broadcast flag mandate is a great way to get that DRM infrastructure deployed) I suspect that the costs of key revocation have already been considered.Dan Lanciani ddl@danlan.*com
