Synergy

Share one mouse and keyboard between multiple computers.

Synergy is free and open source (free as in free speech), meaning you are free to run it and redistribute it with or without changes.

Just use "hm conf" and "hm build" to compile (./hm.sh on Linux and Mac).

For detailed compile instructions: https://github.com/symless/synergy/wiki/Compiling

Happy hacking!
