Dave,

>From your description, it sounds like, in your use case, you are the identity provider and the service provider, which leaves you pretty free to skin things however you please and also use the SAML protocol to communicate between the customized login pages and the internally hosted products.  You could do something custom like you describe but be very careful of the security and phishing implications of your design.  SAML itself is explicitly designed not to capture usernames and passwords at the service provider.

If your only goal is to customize the login page presented by the Shibboleth IdP based on customer branding and other internally hosted products, you can do that very easily with a single IdP and no capture of credentials at the service provider.

Hope I understood your use case,
Nate.
