  I would wave my hands vigorously, and say that's the problem of the IdP.  If 
the roaming federation requires CUI (e.g. OpenRoaming), then it's up to the IdP 
to follow those requirements.

  So it would have to find some way to generate a CUI, and associate it with a 
user.

  I suspect that's a solvable problem.  The packets contain a static MAC 
address, for example.

  Another one is for roaming federations to simply ban EAP-PPT, if that method 
is unable to satisfy their security / regulatory requirements.
