in reply to Client prefers java, but wants to hear a case for Perl

I would play on:

I think you will lose, though. I have tried to argue this exact case with several big clients, and lost all arguments (might be my fault, of course). Try to define a cut-off point to decide how much resources you will spend on trying to convince the client. Otherwise this might become an acquisition resources black hole. (Extremely sorry to say this, but it is my experience.)
