Keyhotee is part of the BitShares ecosystem infrastructure. While serving its primary function as a secure way to interact with people and DACs, it will also serve to draw in new customers. Keyhotee is intended to go viral as every user encourages their frequent correspondents to use the tool for privacy. If everybody recruits just three friends who recruit three friends who recruit three friends... it spreads around the world.
Then all of those users learn about the new free world of unmanned companies.
So it is part infrastructure and part marketing ... both clearly valid uses of AGS donations which grow the value proposition for all stakeholders.
