That's today's method, more or less. It doesn't address my needs. The name you pick for your key may or may not mean anything to me. It might be pronounceable, giving it some advantage over a radix-64 string, but it might also be non-unique, making it worthless as an identifier.
What means something to me is whatever name (or symbol) I assign to the person behind the key in question. That's the one in my mind and therefore the only one of interest to me. You, however, don't know what's in my mind. You don't even know my preferred symbol set.
Why not give it two names? A local name that could be a icon or something, and a universal name (i.e. MD5 hash of key) -----BEGIN PGP PUBLIC KEY BLOCK----- Version: 2.6 mQBtAzCNppQAAAEDALhWZl7IuGZ9zZT5bACo0b/1L0Nv0C72vKHIO3IHh+cwpHHa 2Ozb9aeO0UvXGwkkZIYgUm0EvmzKh7yb1GTLvBp5kXpR3I9w+Yj4LGlBDERpUWw6 x4ED49pwDnz1Hl5FBQAFEbQYYXNoIDxhaHVwcEBwcmltZW5ldC5jb20+ =PtJK -----END PGP PUBLIC KEY BLOCK-----
