It uses its own protocol and its own rights management system and is designed to be totally independent of Windows file sharing.
The embedded download manager supports the resuming of aborted/incomplete downloads. The Shares includes a tight permission control that allows each Tunngler to choose the shared folders and assign access rights. The app Shares is a cool feature of the integrated messenger that allows secure file transfers via a highly encrypted proprietary protocol. You will never see a complete list of supported programs-games because it would be too long.
The game platform is even more: you can use the Tunngle LAN emulation with virtually any program that has IP based network capabilities.
