Instead of export/import, you can also transfer the signed key through the
keyserver network:

    alias gpg-sec="gpg --homedir /media/myusb/gnupg"

    gpg-sec --search-key <contact-name>
    gpg-sec --recv-key <contact-id>
    gpg-sec --sign-key <contact-name>
    gpg-sec --send-key <contact-id>
    gpg-sec --delete-keys <contact-name>

    gpg --recv-key <contact-id>

Does this make sense?
