I agree. This is exactly what I proposed in my talk in Dijon.
The server maps a revocable copy to the cap server. The cap server
maps another revocable copy to each client.

I agree again. Server and client must agree on the same cap server,
which they both must trust.
Note: Not sure if me agreeing helps anybody. I am dead tired (I beat
Jonathan's four hours "last nights sleep" by one hour![1]). But in light
of lots of confusion and back-and-forth, some people may find it
helpful to see some agreement once in a while :)
Thanks,
Marcus
