Limiting access to paid subscribers

I would like to make a book available for download from a web site in PDF format.
How do I limit access to those people who have actually paid for the service?
Also could access be allowed from only one computer to prevent people from forwarding passwords, which I assume would be provided to paying customers, to others?

Is there a system/company/facility for this somewhere?
