There are two aspects.
1) In the Circuit Proxy case, it would be good if the Registrar was able to
   point the Join Proxy at a different device.  Or rather, decline to serve
   it, "too busy".  M_FLOOD/M_DISCOVER does not provide for this.

2) In the IPIP case, it might make some implementations easier if the
   Registrar was aware of the Join Proxy before the traffic arrives, so
   that the Registrar could configure the appropriate virtual interfaces.
