Having trouble setting up Distributed Processing / Qmaster

Question

Hey Guys,
I was able to (at one point) use Compressor 3 via Final Cut Pro Studio with Qadministrator to allow Distributed processing either via managed clusters or QuickCluster - both worked on both macs (a 2007 2.6Ghz Core 2 Duo iMac and a 2009 3.06Ghz Core 2 Duo iMac).
I just upgraded to Final Cut Pro X and Compressor 4. As far as I can tell, the Qmaster settings now reside in the Compressor application itself, so I tried setting it up as best as I could using both the QuickCluster and managed cluster options (very similar to when using the older Qmaster) but no dice. I can see my controller's cluster from the secondary iMac, but it always displays submissions as "Not Available" and it does not help with processing. I've tried everything I can think of - I tried using FCS Remover for the older version of Final Cut, I tried looking around via terminal to see if there are any residual files & settings prior to the FCPX install, I've tried following as many instructions as I could find (including apple's official documentation on Compressor 4 on setting up a cluster) but NOTHING seems to work. I'm at a loss!!
Unfortunately, any documentation or refrences to issues with Qmaster / Distributed processing is related to older versions of Compressor and whatnot.
Can anyone help or have any suggestions? I have no idea how to get this working and I am having trouble finding anything useful online during my research
Perhaps someone is familiar and can help me set it up correctly? I'm verrrry new to Final Cut in general, so I appologize in advance if i'm a bit slow but i'll try to keep up!
Thanks,

In spite of all Apple's hype I'm not sure distributed processing is actually working.
First I ran in to the problem with permisions on the /Users/Shared/Library/Application Support folder.  There's some info about that in this discussion.  You'll need to fix it on each computer you're trying to use as a node.

Then I finally found some decent documentation on Compressor 4 here
  http://help.apple.com/compressor/mac/4.0/en/compressor/usermanual/#chapter=29%26 section=1
However no matter what I tried I could not get the compression to spread across more than one computer.  I tried managed clusters, quick clusters, and even "this computer plus".  I was testing on a mac pro, a mac mini, and a macbook air.  I could disable the mac pro and the processing would move to the mini, disable the mini and it would move the the macbook air.  No matter what I do though it won't run on multiple machines.
I'm also having trouble doing any kind of compositing in FCPX and getting it to compress properly.  I see this error
7/20/11 11:07:42.438 PM ProMSRendererTool: [23:07:42.438] <<<< VTVideoDecoderSelection >>>> VTSelectAndCreateVideoDecoderInstanceInternal: no video decoder found for 'png '
and then I end up with a hung job in the Share Monitor that if I try to cancel just sits there forever saying "canceling".
I'm seeing a bunch of Adobe AIR Encrypted Local Storage errors in the log too.  Don't know what that has to do with FCPX but I'll have a look and try and figure it out.
