I suppose one thing that we can take away from this is that YADIS should
specify some behavior for this. YADIS is a layer of indirection in
itself, and is a lot more flexible than OpenID.

Even something as simple as specifying what to do in the case where the
consumer gets back a redirect response which also has an
X-YADIS-Location header field. (Don't bother following the redirects and
just fetch the YADIS document?)
