Thank you for the link -- I suppose it should've been obvious you'll have some use for command line tools internally, if only for automation (but automation is important, how else can my backup cron job let me know it's completed/failed? :-)

Not so good that you don't (currently) interop all that well. I can understand that gpg/mime is a bit hard, and have some properties that aren't great (metadata/subject header...).

As for plaintext being "broken" when reaching gmail, I suppose I've grown to be a different kind of pragmatic lately. Lets put it this way: I still enjoy postcards, and while (some) encryption is trivial (with the right tools, some of which you are building!) -- I really don't need "another messaging app" (but secure!). I need email that is easy to secure/so easy that always encrypt is useful.

Then again, most of the email I send and receive go to public mailinglists -- without clearsigning, I'd have no use for your product (yet -- none of my private contacts use gpg, and are likely to move to your platform just to get it).

That's not to say I'm not interested to see where you end up, and wish you all the best with your project!
