A few of the features that Tinc has that makes it useful include encryption, optional compression, automatic mesh routing (VPN traffic is routed directly between the communicating servers, if possible), and easy expansion. These features differentiate Tinc from other VPN solutions such as OpenVPN, and make it a good solution for creating a VPN out of many small networks that are geographically distributed. Tinc is supported on many operating systems, including Linux, Windows, and Mac OS X.
