Depending upon the IP implementations of the other Sure, I'll make sure this is going to work fine.

I'd like to live complications such as this for a later stage. I'd say if you have a multihomed machine you better know how to configure it; the primary target for my work are laptops and other clients. That is not to say I don't care; rather, I need to limit how much I chew at a time. For now I only work on one interface.
