I could consider use for this tool, since many times I travel with a mini laptop, capable of only 1024x600 resolution, so canon applicatin won't even run the installer. During this trips, (when I go back to the hotel for a rest) I'd like to review my shoots and discard the unrecoverable ones or the ones that are clearly bad enough (not good enough to keep). This is a task much more comfortably performed on a 10 inch screen rather than on a 3 inch.

The proposed application could allow me to review my shots while charging my camera's batteries.

Also, I guess this web client could run in several browsers, including those on tablets, which are even more comfortable to use, lets say, in bed after a whole day hiking with a backpack full of equipment.

I recently has another ocassion for use of similar technology: I had just shoot an event, and I was asked to project the pictures right away for the attendants to enjoy while they were having a brunch. Awfully I realized that I had forgotten to press "OK" when I selected "RAW+JPG", so the shots were only RAW. I could not project the pictures because when the computer was conected to the projectors, the resolution was unavoidably set to 640x480, not enough for the Canon apps to run. The proposed raw previewer could have saved my neck, specially if it had a "slideshow" mode...
