We have just announced the Acquisition of "Kidaro" an interesting technology that I have yet to get my hands on.  I know that both Justin and myself cant wait to see how this works and functions.  The deployment of Kidaro will be a component of the Microsoft Desktop Optimization Pack.  Kidaro builds on the value of Virtual PC and from my understanding helps to address application compatibility issues through OS Virtualization.

Full Press release can be found here:

Looking forward to getting to see and use this technology.  More information to come I am sure.
