KeyComputing introduced its X-Key 2.0 Exchange Edition this week. More than just a USB device, this phallic looking device houses a full 32 bit processor and seamlessly synchronizes your e-mail with Microsoft Exchange without requiring a single configuration change on the desktop. Plug it in and KeyComputing???s custom built mail client will open your encrypted e-mail stored on the X-Key and then attempt to synchronize with your corporate Exchange installation using OWA???s WebDAV capabilities. Documents and the applications necessary to work on them (Word, Excel, etc???) are all neatly compartmentalized on the USB device and KeyComputing promises that all traces of your activity, including the browser cache and documents in temporary directories, will be removed when you disconnect.
