The attack I'm actually concerned
about is one in which the attacker takes the known list and precomputes all possible seeds and then
determines which input list has the highest probability of a favorable nomcom and then does strategic
withdrawals to produce that list.

Ah, I see.

Given the common practice of choosing several large-scale lottery systems this seems infeasible to me. YMMV of course.
