Remember there are two form of ENUM .. the 'classic ENUM" of RFC 3761 and e164.arpa and the carrier ENUM which are private instantiations of enum trees using the technology of 3761. Carrier ENUM which is essentially a replacement for SS7 and Global Title Translation is doing just fine and deploying rapidly for applications like MMS/SMS routing etc in carrier networks.
IMHO this just cannot be stressed too much. Actually, Rui's whole set of questions needs to be separately applied to both flavours; e.g. "Do users understand it and are willing to pay for it? Do companies understand it and are willing to pay for it?" wrt. Infra ENUM puts operators up as users and/or companies. A first idea of an answer might be heavily related to the interconnection and termination regime in a certain country as well as the (non-) existence of number portability - and how this is technically done.
