Amazing. This stuff needs to get out there more. Too bad I don't have permission to reveal more details.
It would be interesting if you could set up a meeting between a Perl advocacy group and businesses with Perl success stories like that, given the right price/agreement the company might agree to have the story published. Perhaps this is a bad example because it sounds like the company's management made a mistake by hiring the Java team in the first place, but I'll bet that you (and others) know some good stories that would reflect well on a company.
Just a random thought before bed. :)
