Thanks for the useful response. I'd suggest putting these benefits in the Safe page instead of just deferring to a much more complicated page on EncFS as to the "pros and cons".

As far as WebDAV, are the URLs never exposed in any way? A user might paste it into a third party program which doesn't use the Windows client. MS might also make changes if this isn't a documented or supported view. I'm not saying it's definitely a flaw, it just seems a bit scary.

Out of curiosity, how are large files handled? Like if I move an HD movie file into my encrypted store then watch it - does my commit suddenly shoot up?
