While better but still not 100% foolproof, the Canon cameras that I  
have can be updated by first copying the firmware file into the same  
memory card that holds the photos, and then commanding the camera  
through a menu to update firmware. It does take away most of the  
"scare factor" when updating the firmware.

That being said, by now there are probably amateur rigs that update  
firmware through the ubiquitous USB memory stick.

A memory stick could be a good way to save menus and configs of a rig,  
too.  But you would need to add the cost of a USB connector and  
perhaps an additional $5 AVR microprocessor.  That could translate to  
a burdened $20 on the end user, but it can save on support phone calls  
and companies can perhaps eat some of the margin :-).
