robotech_master : I mean that you have to set up DropBox so that your Calibre library folder is shared in the DropBox cloud, and set up as public : basically, either put it in the My Dropbox/Public folder, or make a symbolic link from your actual Calibre library folder to something in the My Dropbox/Public folder (in a Unix, use
ln -s, in Windows use
junction).
Kilroy : thanks for the compliment, it's really nice to see that I helped so many people ! Also, regarding the metadata.db, while it's locked Dropbox won't be able to publish it, but as soon as Calibre exits (as you said, in fact) it will be released and Dropbox is smart enough to quickly publish it (maybe this is the problem Devon was speaking about yesterday ?).
Ortep : I tried Live Mesh, and while it's nice to have 5Gb of free space, there is no Mac client (yet) and (more of a problem) I didn't find out how to get a public URL to a file in the Live Mesh cloud ; did you ? I submitted a ticket to Microsoft, but as far as I know them I'll never get an answer
