We should probably also include the only existing global, open source, standard value transfer protocol and its identifier: Ƀ

+1 for the stratified identifying options
-1 for the brand specific stuff

Another way to think about it might be to adopt a symbol that explicitly represents a namespace outside the DNS system?

Could !username mean, look my identity up on Telehash?
So the discovery protocol may be something like:

IF identifier starts with '!' lookup on Telehash
ELSE IF identifier has the form user@domain lookup using WebFinger and fall back to Telehash
ELSE IF identifier starts with '@' lookup on Twitter identity service fallback to medium.com<http://medium.com> identity service
ELSE IF identifier starts with '$' lookup on cash.me<http://cash.me> identity service
ELSE return not found

The last two are not realistic for a global standard but I'm sure Twitter, Medium and Square would like them

It does make me think that an identifier like adrian$hopebailie.com<http://hopebailie.com/> could be a cool standard though and would imply that my IdP is at hopebailie.com<http://hopebailie.com/> and my identity key is "adrian”.

adrian£hopebailie.com<http://hopebailie.com> is way cooler. A currency symbol that applies to only a few countries isn’t going to work.
