Given the potentially controversial nature of this feature, it's maybe 
best to almost completely isolate it from the base system and make it 
into a port.
When this port is installed and when some special environment variable 
points to its executable, shells would call this executable when an 
unknown command is typed by the user.
Such implementation should leave all parties happy. People who hate it 
just wouldn't install this port.
