Dear Mick.
My CCD uses a parallel port so I am not the best to give an opinion but I don't see what difference it would make. Even with my camera downloads are about 15 secs for the highest resolution. Subframes are much faster. When you are doing 3-5 min exposures waiting 15 secs at the end is not important.
I assume the advantage with firewire would be speed but even with webcams doing video exposures rather than stills I can't see a time when you need more than about 1/30 sec exposures. This is perfectly good for focussing or planetary imaging. There would be little advantage going faster as this speed will "freeze the seeing". Most of the objects we image are not that bright to need faster.
