Hi all,

I was present in the discussion Brian mentions and I agree with him.
EOxServer seems to be a well organized project and I feel it should be 
included in the disk, initially as beta software for version 6.0. This 
would mean no default installation but installable by the user with 
instructions through a quickstart document.

Stephan already created an installer for the disk and I had a chance to 
test it against alpha2.

Best regards,
Angelos
