I'll clarify. I mean that software that's dual-licenced, usually grants unlimited usage within the organization. Essentially you bought it, so it's yours to do with as you wish---though you can't duplicate it and give it to others on its own, you have to bundle it with your product.

If the licence is more restrictive than that, then it is likely the business will fail because if we have to jump through hoops, we might as well (a) use another product, cost isn't a factor or (b) use the copyleft licence and hire lawyers.
