It would have been nice if ToR used onion://drugmart rather than 
http://drugmart.onion, but we lost that fight a long time ago.

I have occasionally wondered whether we could define an agreed set of 
levels for DNS-ish name semantics, e.g.:

* application data stream (onion)

* resolve to a perhaps nonroutable IP address that can connect to 
a data stream (various LAN level proxy hacks)

* resove to an IP address that acts like a real IP address (most DNS 
resolution behind a NAT)

* resolve to a real IP address (DNS resolution without a NAT)

These are just examples, please consdider the overall idea, not the color 
of the bikeshed.
