[OpenID] OpenID Implementation

[Jonathan Daugherty]

# It's true that OpenID 2.0 runs a PHP implementation ragged - it's a
# difficult and complex specification to implement so finding an
# OpenID 2.0 (not just 1.1) library in PHP is limited. JanRain has at
# least an RC, and I'm hoping to hit Alpha before month end. I don't
# have a release date for ZF 1.1 yet - so that's likely a bit further
# down the road.

Actually, OpenID 2 -- contrary to widespread belief -- is not that
much harder to implement than OpenID 1.  (Which is to say, OpenID 1 is
not easy to implement *correctly*.)  One reason for the lack of OpenID
2 implementations in PHP is the current draft status of the spec.  We
will soon be releasing a draft 12 implementation of OpenID 2 in PHP;
the rc2 release currently available is a d11 implementation.
