A couple of completely different solution, with the same theme. 

For flashes that are not yet actually soldered to the board use a bulk
programmer.  You just need to supply Manufacturing with one file they
blast into the flash before mounting on boards.

Does your device have JTAG. Industrial JTAG programmer will be faster
than serial port, or JTAG parallel port dongles.  Again you just
supply them with one image for them to download into the flash.

I've found that manufacturing understand these sorts of things because
its nearly all automatic, no brainer. Plug in a cable, hit a button,
wait till the light goes green.  Having to use a keyboard they don't
like.
