The acquisition of Israel-based Kidaro was announced a couple of weeks back, and has just gone through. The technology will be introduced in the near future, and will form part of the ever-expanding Microsoft Desktop Optimisation Pack (MDOP) to provide even more value to customers with, or considering MDOP. As per usual, we lose the cool naming, and it will be known as the Microsoft Enterprise Virtual Desktop, so that means MEVD will be in MDOP, for which you'll need SA (Software Assurance) on top of WC (Windows Client). Acronym lovers rejoice :-)
So, what do we know about Kidaro?
You can read all about the MEDV technology here: http://www.kidaro.com/technology/ and here: http://www.kidaro.com/technology/advantage.php
Trust me, when you see it in action, it is very cool indeed.
