You mean the part of the README where network mode is described?  As in:
%< Snip ==============
* conf/network.conf

     This is the file used to configure Crack for network running; this file
     contains lines, each of which has several fields:

         host:relpow:nfsbool:rshuser:crackdir

     Where:

        o host
          This is the name of the host to which Crack should "rsh", in order
          to despatch a job. There can be several instances of the same
          hostname in the file, if desired, in order to dispatch more than
          one job to a given host (if it has more than one CPU, for
          instance).
%< Snip ==============

Sounds like integrated, embarrassingly parallel operation to me...

Works that way too, back when I used to run crack on passwd files;-)
