unique identification on internet

This story fits in quite nicely with my idea of a unique personal identifier; that is everyone should have an identifier - either their name or other "tag" that identifies them uniquely on the web.  My name is not unique, dgyeo also not unique, so I invented upi:dyd-dgyeo - which so far no one seems to have copied!
