I just checked the source in omnibus-ruby and it looks like 
omnibus-software is very hardcoded in omnibus.rb:

  def self.omnibus_software_root
    @omnibus_software_root ||= begin
      if spec = 
Gem::Specification.find_all_by_name('omnibus-software').first
        Pathname.new(spec.gem_dir)
      else
        nil
      end
    end
  end

Talked with Seth a little and one small step towards this would be to 
remove the hard-coding and allow the project file to specify a list of 
gems to search for software definitions (in-order).  Sources of the gems 
could then just be specified in the Gemfile.

And I had actually assumed this is kind of how it worked already... 
We're definitely making architectural choices in omnibus-software that 
will not take into consideration any downstream consumers other than 
opscode projects...
