I quite agree with Peter's comments. Keeping this corporation as simple to manage as possible is a considerably valuable feature. If we find we need an "activity corporation," it won't be all that difficult to found that, and it's worth noting that *that* organization would need to have a substantially different board managing it.
Not totally Idle thought: it would be nice if the "holding corporation" doesn't need a bank account, as they impose burdens of fees (not huge, but not providing us notable value), and more importantly, impose administrative burdens. Our banks like to impose holds on accounts any time they are left inactive for ~six months, which is definitely a pain. It's a pain for my local LUG, which normally has financial activity only about once a year.
