3. Set a target date for the removal of those TLDs for 10 years in the future
Because this worked for IPv6?
Obviously there are various implementation details for effecting the move, but application-layer stuff will be as obvious to most readers as it is off-topic for this list.
In this case, it's all about the "application-layer stuff" - that'd be the stuff to fail hard - mainframe IP gateways, control systems, Lotus, Domino, etc. BIND is fine. Even most of the PHP apps would (should, maybe) be fine. But that's not runs most of the gov.
Regarding the time period in #3, decommissioning a TLD is harder than you might think, and we have plenty of extant examples of others that have taken longer, and/or haven't finished yet *cough*su*cough*.
Do we really have any prior examples that are even .1 the size of the usgov public system? Again, I'm not just referring to BIND and Windows DNS (and probably some Netware 4 etc stuff) - this would be web, soap parsers, email systems, vpn, and all of their clients (public, contractor, and gov). Anything close to what y'all are talking about?
