Distributed rendering

Hi, I have a spare computer not doing anything, and would like to know how I can make Blender pass off half of its rendering jobs to that. There is the ‘Render Daemon’ button that sounds like it should do what I like, but I don’t know how to use it. Can anyone help? If it makes a difference, both my desktop and the spare computer will be running Linux.

Cheers.
