Two approaches for pay-per-use software construction

This paper describes two architectures for building pay-per-run software systems: the download-once approach and the dynamic-download approach. These are systems that allow the user to pay for each execution of an application, instead of buying a more expensive user license. This is a new model for software distribution in which developers charge small fees for each execution in order to increase their user market. We detail each component of the architectures and compare both approaches.
