@Tristan,

The OAuth attack scenario is similar to trust one:

* Trustee creates an OAuth authentication delegation (with elevated privs)
* ReAuth with new OAuth based delegation.

Alternatively, someone authenticated with an OAuth delegation could:
* Create Trust with elevated privileges
* ReAuthenticate with new Trust.

The fixes Adam Young has provided eliminate both of these alternate attack vectors.
