To clarify, passive federated signin to OWA works by the client
starting with a request https://mail.foo.bar/owa/ and following a
redirect over to the ADFS2 STS, which handles authenticating the
client (via one of Kerberos or forms-based auth), the result of which
renders a new HTML form for the client to push its security token back
to the OWA app, and I wouldn't expect RPC/HTTP or ActiveSync clients
to be able to follow those steps out of the box.  But, maybe they
can--is there any way to make those endpoints federation-aware?

In addition, these clients would need to have some additional hints
during setup for identity provider-initiated sign-on, in the case
where some other environment is responsible for creating the user's
token (i.e., a pure passive federated signon would not know the
current user's IdP).  Please let me know if I'm not making sense and
I'll break down and make a diagram...
