I forgot to mention no auto-summary, but you already knew that, didn't you. :)

Yes, secondary ip addressing with EIGRP no split-horizon seems to be the simple
st working solution. I came up with something involving HSRP, but now I'm think
ing it just made it more complicated without really making it better. The EIGRP
 no split-horizon was the key to part 2.

This should be possible -
Set up secondary ip addresing with 10.1.0.0 as primary.
invoke EIGRP with no split-horizon

I know eigrp has an issue with secondary addresses but this should
work. Try this and let me know. What about sub-interfaces??
