[ppml] PI assignment subdelegation?

[Kevin Kargel]

Isn't this exactly what the private ASN implementation of BGP is for?
Though as long as company A is a separate entity, I would suspect they
would retain their ASN even if they did relinquish their original IP
net.  That way company B could re-assign a network to company A to
manage independantly.  

I suspect that resistance to relinquishing the original allocation would
be strong due to the traumas of renumbering.

What you outlined is certainly possible.
