                    I know this is a pretty non-standard use.  We're in
                    the middle of a migration of our services layer, so
                    we're kind of an outlier when it comes to typical
                    usage patterns.  We've talked through simply
                    handling this failover manually using a single
                    provider, and we can by with that for now, but we're

                @Bill I think some kind of stackable configuration like
                the authenticators have could be really useful for us. 
                If we could mark providers as 'alternative' or
                'optional' in the same way it would give us what we
                need.  Anyway, just an idea.  At the end of the day I
                think we're after a way to customize the way in which
                federation providers interact with one another (or
                don't), whatever that looks like.<br>

                                              </ol>
                                              <p>Where ProviderB is a
                                                fall-back mechanism
                                                containing the same
                                                logical userbase as

                                                      then ProviderA
