We have eCash now, why not send emails to merchants that accept darkcoin and ask them to enable gpg email.
This will allow us to buy things and have them shipped totally anonymous.
Once people see us buying things totally anon, people will come running!
How would a gpg mail help you to ship anonymously ?
Each merchant has to comply with local laws. And to ship something, ithere has to be some name and some address, right ?
