Programing a prop when you have no propplug

How do you program a prop when you do not have a 3904 or a propplug? Chaosgk has a propmodule-us_sd and a usb prop protoboard. I am writing a boot loader so he can load new code through uSD card on the propmodule but first he some how needs to be able to load it.

I was thinking he could probably with short wires jumper P30,P31,Reset, and VSS between the 2 boards power up the propmodule only and use the usb connection on the protoboard to program the module.

I do not have a usb protoboard so I do not know if this would work. Anyone know or have a better idea?

    Program the EEPROM on whatever board it is he *can* program, then use load the Propeller_Loader program to ram and use that to program the other propeller via 3 spare io pins.
