Once #2519 (lattices in the poset sense) is merged, I was going to suggest modifying Sage matrices to support lattices as well as rings. (The booleans are a lattice). This might end up being totally new code, since most current Sage matrix operations are meaningless on matrices over lattices; but matrix addition and multiplication are well-defined.
