how does that work as a consumer/very small business? they have no proof that I'm running their software, they would be never be able to get a warrant to search my premises, and if they ever stepped foot on my property I'd have them done for trespass. I can believe there's a contractual term in the volume license agreement that allows them the right, but for that they be giving you a significant discount, which seems fair.
