Olpe, Germany-based Netline’s Open-Xchange Server technology was the basis for SLOX but is being released under a commercial license with version 5 in March. Novell announced late last year that it would discontinue SLOX at this time in favor of Open-Xchange.

Netline Open-Xchange Server 5 will be supported and maintained by Netline as well as Novell when running on top of its SUSE Linux Enterprise Server operating system, and will now also be available for Red Hat Inc’s Enterprise Linux for the first time.

Netline announced that the product will be available for the recently released Red Hat Enterprise Linux 4 in April, with the German company providing installation support and maintenance for the product running on both SUSE and Red Hat.

Other Linux distributions are also being considered. Netline CEO Frank Hoberg has previously told ComputerWire that the company was particularly interested in partnerships in Asia.

Also now available is the beta of Open-Xchange version 0.8, the open source version of the product for developers and open source specialists that require less support, as well as beta Connectors to connect the collaboration platform to Outlook and Palm.

Open-Xchange 5 will be priced at $850 for 25 users on both Novell SUSE and Red Hat, with one-year maintenance, installation support, the Outlook and Palm Connectors, and a five-year guarantee, with maintenance subscription fee of $25 per additional user.
