I'd like to use the camera connection kit to download photos from my camera and batch transfer to WebDAV or FTP plus be able to easily batch delete photos from the iPad. IMHO the stock photo management on the iPad sucks.
Goodreader might be the answer to this problem as well. It can import photos from the Photos App and upload to WebDAV or FTP servers. I doubt you'll find the process that smooth and slick though and there might be a dedicated App that does it better.
You can batch delete photos by tapping the icon at the top-right of an album (box with arrow pointing out of it)
