I was reminded today that initial and terminal underscores in hostnames
break DNS lookups slightly (e.g., compare http://foo_.scripts.mit.edu/,
http://_foo.scripts.mit.edu/, and http://foo.scripts.mit.edu/ in your
favorite browser, or Firefox if they aren't different). Given that
scripts.mit.edu and mail.mit.edu turn usernames into hostnames, has
there been talk of disallowing initial and terminal underscores in
usernames (and maybe other locker names)?
