Sure, just add "keyring the-other-keyring.gpg" to your gpg.conf file
or give --keyring on the command line.  By default, the keyring is
expected to be in your .gnupg directory.  If you want, you can give a
"/full/path/to/the/keyring.gpg" to the keyring command and then it
will look anywhere you like.
