In the end, it looks like EIGRP doesn't like something and removes the incoming route advertisements, and my google-fu has not yielded anything that points me in the right direction.
I have yet to configure any authentication, to make the setup simple for the moment.

I could be wrong here, but it looks to me like both switches have the same subnets defined. If I'm DUAL I'm going to remove a route I learn from you if I already have that subnet locally connected.
