I wonder if you directly approached amazon and asked if you could use your own browser agent id that would allow calibre to work or maybe if for those with amazon accounts some way for the metadata plugin to login with that users account to not have the captcha get in the way. I'm not sure how they would view calibre though as I think they would rather you left your books on their cloud other than when it is on your kindle. Not to mention the DRM issues with the third party plugins available for calibre.
On second thought they would probably love to have you approach them and sign a contract restricting those features from being available to make metadata work. I would be scared as shit to ever sign a contract of any kind with them. I have the feeling they would eat you alive on the backend. They seem to be that kind of company.
