one license for every two machines.
So is it 1 licence per 2 render nodes or one licence per 2 computer total?
5 workstations + 6 render nodes = 6 licences? I would need just one more.
6 render nodes = 3 licences? I would need 3 more.
Because of licensing changes with CS5.5 by 3rd party suppliers you're allowed 2 installs per license. If you want to add one more machine, that's 11 so you'll need 6 licenses.
