Moving from eRoom to Groove+SharePoint collaborative environment

Back in 2004, I had done a small evaluation project for a client who wanted to move from eRoom into a Groove+SharePoint collaborative environment. It was an interesting project and much was learned from it. I had very briefly mentioned my findings at Eli Robillard's blog posting HERE. Since then, I have received almost a hundred emails  about it. I have posted that document HERE (it has been edited to remove client-sensitive information). Much has changed within eRoom, Groove and SharePoint - this year will see new & improved versions. Hopefully, I'll get to work on these again.
