Thanks to ZatzNotFunny for mentioning it.
And for those who want more details, ChuckyBox at TiVoCommunity.com posted this link to FCC documents which show the docs, the internals of the adapter, etc. (I’ve had that link for weeks, but I agreed not to share it until TiVo announced the adapter officially.)
