It runs on Linux, Mac OS X, FreeBSD, NetBSD, OpenBSD and Windows and needs a TUN/TAP device. The bandwidth is asymmetrical with limited upstream and up to 1 Mbit/s downstream. This is meta-package to install both client and server. It also contain three documantation files: CHANGELOG, README, TODO.
