The only distinguishing factor of the 4-corner is the "peerwise trust
relationship", which is certainly out-of-scope for XKMS... which leaves us
with an environment that supports referrals (even less Identrus-y).  Without
referrals it will be more difficult to separate complicated trust models
(cross-certification, bridges.. etc) from the trust relationship between
client and service.  This separation, I think, is tantamount in shielding
end entities from more complexity than necessary.  

Other trust infrastructures could benefit, as much as Identrus could, from a
referral mechanism (I'm not quite sure what the difference is between
referrals and server chaining).  Does anyone else agree that a referrals (or
server chaining) requirement should replace the 4-corner requirement?
