Xserve G5 Cluster Nodes and Built-in distributed encoding in Compressor 4.

My IT friend just handed me down a rack full of XServe G5 nodes. ( They left the Apple camp as the result of Xserve being killed by Apple - i wonder if Adobe or Avid makes any highend servers boxes. LoL ). In the past running a render farm under QMaster was part voodoo part witchcraft. Apple is advertising " Built-in distributed encoding " as one of main features of Compressor4. Has any one tried to install compressor 4 on Xserve non-intel machines ? Where do i get the Qmaster from download file that App Store automatically dispatches to my NLE machine ?
