M3 SDK alternative

There's a great post over on the Smart Office blog about how to build Smart Office applications when you don't have access to the Smart Office SDK.  It would be great to see wider distribution of the Smart Office SDK, as it allows developers to quickly and easily extend the core functionality of M3 using Visual Studio, but this is the next best thing.  All that appears to be missing is the logic for deploying a Smart Office package in LCM, though that appears to be a zip file with a manifest so should be able to be reverse-engineered.
