I would very much prefer to see a solution where you can have policy to 
limit what is being published and to where, rather than the very binary 
"use ULAs for Internal resources". Apart from the fact that I do not like 
ULAs, I would also like to see more granularity and to enable the 
possibility to have zoning within the home network, for instance to have 
guest networks.

So we need to enable possibility to control propagation of service 
discovery information, we need packet filtering, and we also need some 
kind of "identity" for the devices so they can interact with all of this.
