ViaTraining, now part of General Physics, creates enterprise learning management systems. Their original system was based in LAMP and they had a contract with Microsoft who, not surprisingly, preferred that ASP.NET and SQL Server be used.

I helped with the port to .NET technology and globalized the interface. Windows Mobile Training was in use for about seven years and typically had about 10k users in 13 languages at retailers like Best Buy.  The system managed their training progress and dispensed incentive rewards.
