ummm... We have 60 computer in our office that are worth using for render engines.  Why buy more?  They aren't used at night, I can render 1 minute of animation in less than 30 minutes of this field of computers... that's using VIZ and backburner.

Vue has issues.  the computer has to be logged into and not locked in order to use it... VUE needs to change their policy and make the render cow run in the background as a service like other render farms.  Their approach on this issue is completely impractical.
