Using the Canon SDK

My next project in the sea of possibilities is to use the Canon SDK to automate camera controls, both with the old PowerShot S10 and with my new Digital Rebel XTi. For the moment, I am without a test environment -- the S10 has a serial cable but requires USB, and my XTi should arrive any day. Once I have the capacity to test my software, I'm thinking I'll make the wrapper classes available (assuming it's in-line with Canon's license agreement).
