Just a heads up; Linux & Mac builds of the client are in the works. The authentication handshake needs some patching up to be mono compatible, but the rest of the core has already been made linux / mac compatible.
Below is a screenshot of snapins working on Ubuntu! (as a matter of fact, they work on any linux distro and same goes for any Mac version). Autologout, task reboot, and user tracker also work on mono with 0 modifications needed.
