If you mean SSO from the desktop on a domain-joined machine that's
certainly possible with the Shib IDP:

Those both mean the exact same thing. And yes, that's possible. You'd
have to add a SAML SP (likely the Shibboleth SP) in front of the IDP
as an HTTP reverse proxy and configure the IDP to accept REMOTE_USER.

Yes. Note all of the above is possible -- including the "transparent
authentication on organisational devices" with just the Shibboleth

Wrong documentation, that's meant for something else.

It documents the pieces that relate to the Shibboleth IDP.
The rest is up to the deployer. (Short version: Put the java servlet
container running the Shibboleth IDP behind Apache httpd and connect
them with mod_proxy_ajp. Add the Shib SP and protect the path
/idp/Authn/RemoteUser on the IDP with the SP. Configure the SP as SAML
SP/RP to your MS-ADFS IDP.)

So you'll stop participating in the UKfederation and internationally
(via eduGAIN)? I wasn't aware MS-ADFS could interop (without lots of
kludges and hacks) and make scalable policy decisions (e.g. REFEDS R&S
