Irish Army's software choice: Microsoft v Novell

Apparently, the Irish Defence Forces (army, navy, overseas peacekeeping missions) currently relies on a mix of Novell Netware and Microsoft Server 2003. But it wants to switch to one or the other for the entire force. As per today's tender:

"The Defence Forces now requires a single software reseller to supply all its standard software requirements and assist in managing its licencesing infrastructure. A framework contract with the successful bidder will be put in place for 3 years and should be comprehensive enough to cover all future software requirements."
