  The requirement to keep authentication credentials private, which is

  Is there a document describing that?  Will implementations be
interoperable without a document?  What security and privacy issues are

  Roaming was just one example.  Even with roaming, there are multiple
roaming consortia, for multiple purposes.  Standardizing a
cross-consortia method for channel bindings would appear to be useful to
