Hi Deo,
Sharepoint 2007 allows checkout/checkin of documents in a workflows so changes can be more easily merged with Word 2007, but Word
doesn't support simultaneous editing by multiple users on a single file copy.

Some of MS's 'visions' of enterprise social networking tools and real time collaboration would allow folks to share thoughts and
notes and be able to cut and paste from those tools into a shared view of a document.
===========
please can someone please confirm if word has a feature that enables realtime
collaboration. two people working on same document simultanesouly. i have
heard shrepoint could make this possible but dont know how>>
