I've been using this software for about 5 months. It has solved my security worries in an easy way. As I carry a MBP with sensitive data, I had no other choice, but to use FileVault (FV). The problem with that is that FV encrypts your entire home folder, with the big speed compromise. In case you use app with intensive harddisk use, you will get into troubles (for example GarageBand or FinalCut). You could move those files outside your home directory, but that means reorganize the way I use my computer, and I did not want that.

Espionage lets you encrypt only the folders you want in the same way FV does (encrypted Apple disk images) in a way you usually wont even notice there are encrypted. It also comes with some application templates to help you encrypt, for example, all your Mail in a single step (it knows the folders needed to be encrypted and selects them automatically).

The other VERY important thing is with backups. Espionage comes with some integration with TimeMachine , to block the backup of the protected folders and provide a more efficient way to backup them (More info about this on their web page). For now, it has been good enough for me.

It also works with Dropbox.

Support it's also very good and fast.

Recommended in case you need to encrypt some folders and can't compromise the loose of harddrive speed of your entire home volume. Is this is not your case, FV could be just fine.

A small application that adds the basic iTunes controls to the menubar. You can configure the way it looks, like changing the buttons icons to one of many included alternatives, the options on the menu, etc. Very easy to use when you finish configure it the way you want it by using the application. After that, just the iTunes icon remains in the the dock.
You click play and it wil launch iTunes, hide it fast and start playing the first song in your library. From there you can choose one using the menu or simply use iTunes like always and use the controls when you need to pause or skip one song.
For me, discrete and functional.
Thanks!
