The Kolab XML format addresses the issue of interoperability and not
scalability. No format can really do that.

The server hardware, software running on the server and client access
creates the scalability potential/problem. You cannot run 10000 active users
on a 486 with 100 MB disk space, no matter how good your format is. :)

As for 500 seats ... Yes, there are companies running 500 and more users on
Cyrus-IMAP, which is the heart of Kolab server, sharing calendars, contact,
tasks, etc.
