It sounds like you want general APIs for accessing data in web apps. That sounds like a good idea, but doesn't really have very much to do with speech as far as I can tell. To make this a bit more concrete, perhaps you could propose some APIs that you would like web browsers to implement? -- Bjorn Bringert Google UK Limited, Registered Office: Belgrave House, 76 Buckingham Palace Road, London, SW1W 9TQ Registered in England Number: 3977902
