Ha. Try telling a customer that even though he's prototyped his machine with three arduinos (he used three because he couldn't figure out how to do multitasking with just a single one...) in a couple of weeks, it will be a $100k project to spin up a custom circuit board and firmware to do the same thing. And no, we can't reuse the code he already wrote. [sigh]
