Groupware!

In each corporation groupware is needed. But nobody really seems to understand it and use it correctly. No integration between tools, no standards... A totally mess.
There should be some public protocol that could be used to share information between all clients.

In my opinion GW should integrate:

1. PIM
Zimbra
Chandler
HulaEGroupware

2. Project planning
PhpCollab
Netoffice
Microsoft Project
Gantt Project
http://www.openworkbench.org/

Links for these tools

3. Presence & Messaging
http://www.jabber.org

4. Data Sharing
FTP, HTTP, RSYNC, WebDAV

All above should be under the same interface or with different interface but using the same background engine.
There are some web projects and some applications that are trying to accomplish this task but they are really not understanding each other well enough.
