Joe,
Indeed, look at http://www.w3.org/wiki/TPAC/2015/SessionIdeas#Web_Authentication_and_Security

Is the discussion at TPAC going to be in a breakout session? If so — is it scheduled yet?
I would like to attend.

The parameters of those interested in developing this work include
explicitly respecting the Same Origin Policy. Since that security
boundary is widely applied across web applications, setting user and
developer expectations, respecting it is essential to the deployment of
new authentication components. While we usually implicitly assume that
new work will respect architectural best practices, it seemed useful to
add the text here to head off these counter-arguments from the start.

Thanks for the explanation and for sharing the draft.
-1 on that line still, I dont think it is needed.

Preempting counter arguments I dont think is a necessary measure.

This line doesn't preclude federated identity work elsewhere, just not
in this chartered group.

Discussions began with FIDO members who are also W3C members; we're now
inviting broader feedback. We assess consensus later, when we bring
charters to the W3C membership (Advisory Committee) for review.

Thanks.  Look forward to hearing more.
