Stephane original mail stated that he has seen this behaviour on IPv4 
with the
name servers for kura.io and Berts email stated that he knows an 
operator that does that. So while it may not be someone you know it 
like it is done and IMHO it is a bad idea.

patents I don't follow the thread any longer as IANAL and I don't want 
spoil my day thinking about it.

So long
