Office 365 Word does it without the need for SharePoint (both in the Word web interface and the Desktop app). It's terrible, I can't recommend it. The number of crashes and sync-losses we had was ridiculous.
You can collaboratively edit Word documents in Word 2010 and SharePoint:

Also works in OneNote. OneNote can do it without SharePoint, I don't know whether Word can.
