==> Caveats
iftop requires superuser privileges. You can either run the program
via `sudo`, or change its ownership to root and set the setuid bit:
$ sudo chown root:wheel /usr/local/Cellar/iftop/1.0pre4/sbin/iftop
$ sudo chmod u+s /usr/local/Cellar/iftop/1.0pre4/sbin/iftop

In any case, you should be certain that you trust the software you
are executing with elevated privileges.

Error: Cowardly refusing to `sudo brew install`
You can use brew with sudo, but only if the brew executable is owned by root.
However, this is both not recommended and completely unsupported so do so at
your own risk.
