The login shouldn't be a problem for Calibre right, as it's just a matter of using the right url and cookies? There isn't a 'real' login with user/pass combination, just a personal URL.
Also, the rss feeds only cover part of the paper. The opinion section for example - in which I'm very interested - doesn't have a feew.
I would love to be able to schedule Calibre to download the epaper each afternoon, and have it upload it automatically to my reader when I connect it. Is there really no way of doing this? Or should I be asking this question in a different topic
