Devo provarlo al più presto... mi chiedo perchè di cose "inutili" ne parlano in 50, e di cose importanti come questa in pochissimi...
Scoble has been alluding to this for the last few days and it's now out there - Office Live Workspace. This is one of those products I've known about for a while but had to be very tight lipped on. It brings our Office collab on the web story up to scratch and there is more where that came from.
...Summary is this
- store office documents out on the web and collaborate - up to 500mb per user
- access and view Microsoft Word, Microsoft Excel, Microsoft PowerPoint or PDF documents from almost any computer with an Internet connection regardless of whether it has Office installed.
- works for IE and Firefox on PC and Mac
- Create Web-based lists (for example, to-do lists, guest lists and wish lists) and notes.
- Synchronize Contact, Tasks and Event lists with Outlook 2003 and 2007.
- Open and save files directly from Microsoft Office XP, 2003 or 2007 (that's right kids, XP and 2003 too!!) - using client side plugin
- Share your screen and work together in documents in real time using Microsoft SharedView
