Please take a look to this thread:

I found this link:

It contains a document describing LibreOffice extension for SharePoint, CMIS Connector, but I’ve searched for it at http://extensions.libreoffice.org/extension-center/lpsp and it doesn’t exist.

I would need to be sure of how Libre Office is integrated with Sharepoint in contrast with Open Office.
