How can I get CNUT to do more than 4 downloads at a time?

By default CNUT can do 4 concurrent upgrades.  By selecting Update/Configure this can be increased to 20 concurrent upgrades.  To upgrade more devices quickly there are two options:

  1. Use Autoupdate Mode.  This sets CNUT up to be only a file server and removes it from having to orchestrate the upgrade process.
  2. Run multiple copies of CNUT on the same or differenet machines.
