Need recent TCO & ROI studies for OOo

[orspain]

Hello,

I'm attempting to compile some TCO & ROI studies for OOo as part of my master's project involving migration to software libre. I'm looking for links to recent information as most of what I've found is rather old.

Thanks for any information!

As a follow-up to my previous post, I am also looking for recent quality or maturity analysis of the OOo project using existing methodologies such as QOSS, OpenBRR, OSMM.

I've found a BRR for version 2.3 here: wiki.freecode.no/norstella/OpenOffice.org, any other examples?
