Hi Ben, hi all,

thank you  for the reply's.
A documentation how to achieve that, or maybe also concrete examples, 
would be a really great start.
A standard mechanism to allow upstream-facing v6 client to derive a 
portion of the PD and deliver it to downstream-facing clients would 
exactly fit to what I would need.

Thank you for that very much in advance.
