A really smart product would be a SRAM based cart. A blank cart with
say 64Mbit of ram. Put a small boot ROM and a bank swapper on it.

Then when you boot up the small ROM waits for you to send data and
stores it in the SRAM. When its down it uses the bank switcher and
loads the program.

Advantage, super fast loading of the program [also less mucking with
hardware, e.g. you can write more times to it] and no stupid 256kb
program limit. Also you would not wear your system too much by
removing/inserting the cart.

The cons: A small 64mbit cart would probably cost 200$ US or so. The
program won't stay when powered down, it will also consume more power
from the batteries.
