A Survey of ILP Account Identifiers?

Hey All,

There seems to be several different ways to define the format and
characteristics of an ILP Ledger Account identifier (e.g., ILP Address,
email address, URL, etc).

For me, this has led to some confusion as I've tried to reason about when
and where to use which style of identifier.  So, I created the following
wiki page to try to and collect my thoughts and formalize my understanding
of these different proposed identifiers, when to use them, and why:

https://github.com/fluid-money/ilp-connector-java/wiki/A-Survey-of-Interledger-Account-Identifiers

While I feel like this has clarified some thing for me, it has prompted a
few more questions, which I tried to outline in the last section called
"FAQ" -- I provided some strawman answers and counter-answers in there, but
I'm curious if anyone has input/opinions/clarifications/corrections about
what I've put together overall.  Feel free to share your thoughts, and if
there's any interest I'd be happy to move this page over to the Interledger
project on Github if people find it useful.

Thanks,
david
