I think that the /big/ problem here would be finding the right documentation --
i.e. that it's not really a Dolphin problem as such, you'd have exactly the
same difficulties if you were using, say, MS C++.

E.g. scanners are usually accessed via TWAIN, and I think Ian Bartholomew has a
goodie that wraps some or all of the TWAIN API.  But if you want to get the
video stream from a webcam or whatever, then you are entirely dependent on the
manufacturer producing (or being willing to produce in exchange for $$) an API
you can use.  Similarly, you can certainly find public implementations of movie
file formats that you could adapt/wrap, but you are at the mercy of the vendor
of any OCR application.
