Toni, I have one request: would it be hard for you to provide also a MultiUser enabled build?
 Unfortunately, AROS does not seem to be open source anymore (The AROS repository is running on a password protected SVN server, which means that you need to apply for access to it to be able to collaborate in the development. At the request of Amiga Inc., anonymous read-only access to the repository has been disabled
- see here
), so hardly anyone can provide such a build, even if it is trivial
