Demonsaw is a new type of information sharing application that allows you to share your files securely. It's the next leap in the evolution of a free Internet, and the debut of social cryptography. Demonsaw is designed to protect your anonymity and hide what you're sharing. Your IP address is never revealed to the world. Share whatever you want, with whomever you want, without fear.
Every information sharing application over the past 45+ years has had 3 common elements: the ability to upload/download files, the ability to control program flow, and the ability to transfer data. Demonsaw is different from other information sharing applications because it breaks up these different types of abilities into separate network components that act autonomously. By doing this demonsaw creates an extra layer of abstraction that completely secures your information sharing.
Demonsaw is a type of decentralized private cloud network. It takes the best features from centralized applications, like Dropbox, and decentralized applications, like BitTorrent, and merges them into a seamless new type of hybrid information sharing application. By levering your home Internet access, you become your own secure information sharing network.

TellForm grew out of one of David's contracting projects where he was tasked to create a self-hostable, airgapped kiosk for a client in the medicial industry.
Finding no forms to his liking that were as easy to use as TellForm David set out to create a alternative to TellForm. After working on it for a couple of months in the Summer of 2015, he decided to opensource it.
