Platforms The first Portable Context client will be available for Internet Explorer 7 and 8 in Windows Vista and Windows 7. Additional platforms will be supported in the future and we look forward to working with others to develop additional interoperable implementations.
License The client software and a reference implementation of the server will be released under a dual GPL / MIT license. SwitchBook also offers open source production grade servers under commercial and educational licenses. A feed from SwitchBook's recommendation engine is also available on a licensed, revenue share basis for partners with client-side implementations. The standards for the Portable Context will be managed under precepts of the Open Web Foundation, including the OWFa and CLA 1.0.
