Ideas
Might be good to come up with example code that opensource applications can take and easily adapt to their application framework.
Virtually any internet enabled application that is used to contact others can be enum.164 enabled, so that rather then trying to remember 10's if not 100's of different ways of contact in people, you can use a single number and lookup the rest from DNS.
Additional information such as GPG fingerprints and Do Not Call lists can also be stored in DNS.
