ATI believes that the use of Armory or Armoryd, licensed under the AGPL 3, as a backend application that interacts with any information from the Internet, causes all software in between Armoryd and the Internet to also be AGPL 3 licensed. Therefore, the source code is required to be publicly available.
This seems like a rather surprising position to take. It would, for instance, prohibit using an off-the-shelf commercial firewall between Armory and the Internet.
