identity as a URL instead of an email? hrmmmm

Thanks for the link, hadn't seen it before though there aren't a lot of
details on the site.  It seems like they could use both OpenID and Yadis
to accomplish their goal though.

I am not sure if it has been posted on this list yet but at etech I met
Alex Jacobs who developed
"We already use email addresses to identify users and we already use
mail domains to authenticate them (via confirmation emails). We should
use that infrastructure so users only ever log in on their mail domain
server and sites can use those logins to authenticate those users when
they visit."......

So far, no-one has come up with a workable solution for an OpenID-like
system that uses email addresses for identity. Do you have one?

The most common issue with this is that people *don't want* to tell 
others their email address just to access some site, because email is
tricky to reliably filter should someone start sending you loads of crap
you don't want.

I think in the long term the XRID people would like their own crazy 
brand of URI to become the identifier. XRID can be a layer atop URLs, so
if they have success with that then a future version of OpenID (or, more
likely, YADIS) will be able to use these instead of URLs. For now, we're

stuck with URLs.

This is irrelevant most of the time because users don't need to know
that what they're entering is a URL. LiveJournal users just get told to
put in " <> ";
they don't need to know nor care that
this is the URL to their journal.
