<p>looks ok to me. and in a sense, ega does have this result: in any category, arbitrary limits can be made from fiber products and filtered limits (and the terminal object i guess, but let's forget about that), and in the category of schemes fiber products always exist and filtered limits exist when the transition maps are affine.</p>

oh yeah, but this doesn't address the question of arbitrary products of arbitrary (non-affine) schemes. i don't see why those would exist.
