Yes, even for more that should be sufficiant. There are people running
Nut/OS in the internal RAM of the AT90CAN128 (4K), but for sure without
the TCP Stack.

But Yes, it should be fairly sufficient for such a simple task.

Btw: You won't have to "port" that much. I'm quite sure most of the code
will run out of the box. But you will have to make some little additions
to the configurator scripts. For example nut/conf/tools.nut contains the
CPU selection and compiler settings. You should extend this file with
the settings for the Mega1284.

If you need any help, please let me know. I think there are some more
people who would like to see Nut/OS on the Net-IO board.

No :) Try Nut/OS and have fun! :)
