Canon seems not to be responsive to requests (http://www.powershot.com/powershot2/customer/developer.html) for their digital still camera SDK. By any chance, does anyone here have the SDK?

Yes, I do. It is about 50mb. Are you on dial-up or broadband? I can put it on my .Mac iDisk and you can download from there if you like. Let me know.

Thanks, Jeff--I've sent you an e-mail.
