<p class=MsoPlainText><font size=2 color=navy face=Arial><span
style='font-size:10.0pt;font-family:Arial;color:navy'>Good point, Peter. I’m
sitting in a room of LDAP and AD architects at Microsoft right now and your
theory is right on – because of their directory and X.500 background,
they get the value proposition for XRI in seconds. This proves out the XRI Technical
Committee’s experience that, while Simon is right that we have yet to come
up with a compelling way of getting developers _who do not have one of the
problems XRI solves_ to easily understand the value proposition, the converse
is also true: if a developer_has_ one of those problems, then they can turn
into an XRI evangelist very quickly (like the Boeing directory team that is now
very active on the XRI TC).<o:p></o:p></span></font></p>

<p class=MsoPlainText><font size=2 color=navy face=Arial><span
style='font-size:10.0pt;font-family:Arial;color:navy'>Speaking of persistence, I
think it's widely recognized the primary reason XRI was included in OpenID Authentication
2.0 (besides XRDS for discovery) was for its deep structural solution to the OpenID
recycling problem. Yes, once the seriousness of this problem was recognized,
the hash URIs solution was developed so that OpenID wouldn't be completely
dependent on XRI architecture to solve the problem. But most OpenID architects
I know acknowledge that XRI i-name/i-number synonym architecture is a cleaner
and stronger solution – for example it enables a OpenID user to
completely abandon an XRI i-name (or a URL) while still retaining full control
over the XRI i-number, for the XRI i-number to be portable and fully and
independently resolvable from the i-name, neither of which you can do with hash
URLs.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>It’s no secret that other Internet scale
identity frameworks also need these same capabilities, which is why XRI and
XRDS is already the core identifier and discovery architecture for the Higgins
project, and discussions are active with the information card folks.<o:p></o:p></span></font></p>
