Network rendering, for real

Check [Custom Build] Blender pigeon
Basically,

  1. put Cycles (client version) on Clients and run it (cycles_server).
  2. on Master use full build, set Render > Device: Networked Device (enter Network Servers addresses)
    disable firewall or add exclusions - data must be allowed to pass through
  3. Render from Master.

Note: Cycles CPU only

Tested, working fine (stills, animations) – set up only took couple of minutes (to DL, extract, run, enter addresses, render).
