Without hand coding assembly to move the hex over to somewhere execution space, is it possible to read in from the flash/eeprom and execute it?  Theoretically there is no difference between data and code in memory anyways....

huh?

although most large CPU use a von Neumann architecture http://en.wikipedia.org/wiki/Von_Neumann_architecture

many microcontrollers use the Harvard architecture http://en.wikipedia.org/wiki/Harvard_architecture

The AVR happens to be the latter.
