Can you point all of a TLD towards Localhost in a hostsfile?

Is it possible to point all of a TLD (like .dev), towards localhost with the hostsfile and without having to set up a local DNS server? Would be awesome for local web development!

The hosts facility in most operating systems does not support wildcard functionality; you would need to write (or find) a NSS library (or whatever equivalent is used on Windows or OS X) to provide the names.
