Hmm... Sweet, there is a Cluster:: name space on search.cpan.org :) I might rename the module to Cluster::Simple or Cluster::Run. The basic way the module & accompying scripts work is (Aprox, still changing slightly):

• (DONE)Create config ini files
  • host.ini # what hosts to connect to
  • script.ini # what to run on the various hosts and other configuration settings
  • manifest.ini # a manifest of files, which, is updated before the module is run to ensure that the files on the client side & server side have the same md5 check sum
• Scp config files from server -> clients
• launch client.pl process
• Client decides what files it needs and scp's them over
• Client runs the main process.
• If multiple proceses are launched at once, waits for a 'processfinishednnn' to be found in the current directory
• Client scp the diff of the file found in the manifest file back to the orignalserver.
• Server waits till there is a count on the number of clientdonexxx files in the ./runname directory before it returns back ok.

In a crappy custom code, I had a linux & solaris box working together. Trying to figure out how to get cygwin's ssh server to actually work, and then I'll declare victory and move on... :) Note, btw, the main process doesn't have to be perl, it could be your favourite exe... :) Also note, will need to get the module approved by 'legal dept.' before it can be distributed to CPAN. :(
