PocketASP is a system designed to run on Windows Mobile (or Pocket PC) PDA devices and smartphones. It allows HTML and ASP pages to be executed on the device without the need of a resource-heavy webserver.
Rapid application development is therefore possible: small sites can be developed and tested in the familiar PC environment and then be transferred, with no changes, onto a handheld device.
This is a similar system, but designed to run on Windows PCs rather than handhelds. Again it negates the need to run a webserver so making it ideal for running web application on a laptop without a network connection or a low-powered machine.
