You're probably right. Though it would be interesting to know how many people x how much per download would be the break-even point for a "blanket licence" for an operation that I guess wouldn't be looking to make a commercial-level profit (i.e. not looking to rip people off!), and whether that's a price said people are willing to pay. Material for a poll? Along the lines of "It will cost x pence per download if y people sign up for z downloads?"
