I believe both SAPI and DirectX are bundled into a form that is redistributable by developers. However, greedy vendor microsoft has been changing tactics lately so I'm not sure how long that will continue. Afaik these two are basically loadable libraries in binary only, the API is published, the internals are proprietary. You don't even really own the new vista, and it can only be installed on one machine. Upgrade your hardware and pay greedy vendor again ... -- Doug > Is something like SAPI or DirectX, quote part ofthe OS
