Google acquires DocVerse for MS Office integration

Just after EtherPad acquisition, Google buys another startup that works with office documents - DocVerse. This is a plug-in for MS Office applications, that allows to collaboratively edit documents in real time. DocVerse was created by former Microsoft employees. Whether users are working on a document online or offline, DocVerse will track, manages and sync all changes to merge them into one updated version of the document. You can communicate with other users via an IM feature within the plug-in as well. Why Google may need DocVerse? First reason - is to enable full compatibility with MS Office formats for Google Docs, and maybe even to add an option to collaboratively edit documents in Google Docs and MS Office. Second reason - is to use DocVerse technologies to build a desktop client for Google Wave. The purchase price is supposed to be around $25 million.
