Open Source deployment: change management and back office issue

Critical issues of opensource deployment in most office is change management and back office (support). I've been using OpenOffice.org for almost 3 years (or is it 4?) but it's hard to deploy this in the office, even to my own department. 

I know that there should be a culture shock the first time they use this application. They keep asking "How do I do this, as Microsoft Office does". Lack of support from the IT function shall shift them back to old application.

OpenOffice.org 3.1.1 for Mac: first impression

Finally, the "command + shift + left arrow or right arrow" is back in effect in Spreadsheet. It's much more stable (at least until the time I write this post - haven't tried a significant amount of project using OOo 3.1.1 lately).

Now, I'm putting the schedule to shift my staff from Microsoft Office user into OpenOffice user. This is an additional project to the existing change management for working in the cloud project.
