It's been utterly invaluable for SAMLtest, at least.  I think the general use case was for handling folders with large numbers of local metadata files, as are accruing all over the place with non-Shibboleth implementations of SAML proliferating.  Also, read the little bulletin on this Wiki page to see why it's so much better than the FolderMetadataProvider.

That would be MDQ.

Lookup of the IdP once the assertion comes back.

Best wishes always,
