Why is this a danger?

IMO, the ND proxy mechanism effectively does bridging at layer 3. 
What makes you think it will be any easier here than at layer 2?  If 
layer 3 bridging is something that we need, then why not run STP?

There was some discussion of this general concept (zero-configuration 
routing and/or layer 3 bridging) in the Zerouter BOF and on the 
zerouter mailing list...  Does anyone know if that effort is still 
active?
