Exactly.

Exactly.

The architecture of hyperion much more modular like hymalia. The fact, that
there's currenlty no ldap integration does not mean, that it is not modular.

You cannot say something is not modular, just because it is missing modules!

There's currently a lot of components and examples on the way for hyperion.
The server is not completely modular (in the development HEAD) and the
admin/provisioning part already is (in the current stable branch).
We are using OSGi to achieve this modularity. Hymalia does not have any such
modularity at all - except for the gui, which allows to integrate own web
modules -. With Hyperion, not only the server is modular.

The current Hyperion stable gui has support for Netvibes UWA
(http://www.open-xchange.com/wiki/index.php?title=Hyperion_UWA).

The next generation is going to have even more features like themability.

1000 concurrent is of course way below what Hyperion was designed for.

for more details about the architecture.
