-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Ahah. Yes, these are opaque program identifiers and reused over time (small namespace). I'm not sure if they will make it into the digital transports as tagged program meta-information or not (certainly not as a standard, but perhaps by convention over time). The studios are thinking UMID for this same basic purpose, but these are unique over time and space. Either way, however the world starts to unambiguously identify programs, as Harold notes, we should have a scheme for handling them. It is not tv: as currently contemplated, though....
