OneNote 2003 SP1 has wrapped [with real-time note sharing] On the list of new goodies:
"Breakthrough experiences, like real-time note sharing. If you're the only person you know who has OneNote, then this is not of much use to you, but if you work with others, such as in a team, it is very powerful. We do our status meetings using this. One of us invites the others to a shared session, then everyone joins and adds their status to the status page - all at the same time. It is freaky to watch, since the whole page is filled in after about 2 min, with text and diagrams appearing all over the place. Then the whole meeting is way faster because you can read the status and not wait for each person to say all of it. Once I had to be at home and had to miss the meeting, and decided to join a shared session that was going on at work. I could see everything everyone else could see who was actually in the room, and could even add comments and ask questions silently by typing them into the shared note surface. Wow - try doing that over just the phone."
Excerpts from the bullet list of new features:
"Shared Sessions – real-time peer-to-peer multi-user sessions (we had over 70 people once)
Share With Others Pane – e-mail/SharePoint/file share/real-time
Shared Folders for collaboration with others
Much better performance with SharePoint
Copy text/ink/voice notes from Pocket PC/SmartPhone"
Okay, I need a spiffy new Tablet PC now...
