A big operational warning: it will seriously complicate DNS debugging
for the system administrator. Currently, if a customer / user
complains "Not able to resolve www.example.org", I can dig my BIND to
see what's going on and restart / fix it if there is something
wrong. With a big and complicated program, the resolver, on the user's
machine, all bets are off...
