How do you like to read a phone number?

thank you for your complete email!
My idea in about these points:
a) Who now has a freerunner is someone that is a bit an advanced user.
And I think a lot of people don't like all these ambiguities on phone
number. I think a phone number must to be as unique is possible (in must
not be different if I have to be called from a person that live near to
me or from my uncle that live in Japan). So I'd like to force (ok... not
really forced, but encourage) people to dial the number with
international prefix. (but with some ticks to don't press too much buttons)
b) Internally all the number are registered on this format, that I think
is the most correct: +XXXXXXXXXXXXXX, then every phone number is rended
according some rules very easy with spaces, dash, etc.
c) Because I think it can interest someone else, if I have success to
manage it, I would like to separate the "Parse logic" from the main
program logic. In this way it could be used by other programs (If
someone is interested can contact to me). It is for now a Python class.
d) I'd like to avoid to use a specific class for every coutry. For now
(until I will not find some very big problems) I would like to have a
simple big text file with all the configuration. I did for Italy and
seem to be pretty fast.
e) In every moment everyone can remove this formatting funcion and to
fall back on +XXXXXXXXXXXXXX format.
f) I'd like to don't add only formatting information, but also some
other info as country, town, type (fix/mobile) and whatever you want.
