Importing/exporting bookmarks

[riki]

I have searched these forums for an aswer before posting, but nothing turned up.

Is there a way to keep bookmarks synchronized between the Calibre e-book viewer and a hardware reader (Kindle 3 keyboard in my specific case)?

I keep many books "open" at once, so after syncing the Kindle with Calibre, I'd like to be able to pick up on the device from where I left off with Calibre e-book viewer. Speaking personally, I feel this functionality would be especially valuable for technical books, since each book may have several bookmarks (points of interest)..
