Thanks much for the kind words on the boxes and you're right about something missing, but it's actually by design (isn't that what we programmers are always supposed to say?
Seriously though, sky-only seems to be the preferred way to go, then people add whatever they want in the foregrounds. Going the other way, like, for example, putting big tall buildings in one of those stormy sky boxes, would straight off make it useless to somebody wanting a stormy sky for a naval battle being fought on a stormy ocean (at least, until they invent floating cities)
I *have* been outputting matching terrains on some of these things, saving them as .X objects that have matching textures. So we could have the best of both worlds with the skyboxes then -- sky only for those who want it, or mountains/trees/buildings/whatever as a true 3D object around the sides of the box. I babble on incessently about this in the "40 free skybox " thread and there are some screenies in there. It's still a work-in-progress though.
