After about eight years of the whole world using "_http._tcp" you're  
claiming that some hermit somewhere is developing software that uses  
"_www._tcp" instead?

That's about as likely as some hermit somewhere whose TCP stack uses  
IP protocol number 191 to mean "TCP".

Good luck convincing printer companies to update their firmware to  
advertise a different service type to accommodate a non-existent web  
browser that's looking for the wrong service type. If such a web  
browser existed they'd have heard customer complaints for the last  
eight years (but of course they haven't, because this mythical web  
browser doesn't exist).

That's a terrible idea for efficiency on the network, and battery  
life, and I can't see any vendor deciding to do something so pointless.
