I have been looking at Evernote with some interest. My problem with it, and which (I believe) is not solved with your excellent Truecrypt/Batchfile scheme, is that once Evernote is opened, whether shrouded within Truecrypt or not, will still phone the mothership and send your unencrypted(?) stuff to the Evernote data centers. Your stuff may be safe locally, but your stuff is still vulnerable in the cloud. If you want to scan your credit card or bank statements and add them to an Evernote notebook, don’t.
To be sure, I am not against the cloud; putting a Truecrypt container in a Dropbox account and keeping your bank statements in a file/folder structure within that container I would regard as just fine.
Just found your site. Excellent stuff!
