Someone within your organisation seems to be getting confused between server products and desktop products. Foxpro is a desktop product. Another way of looking at it is by replacing the word "FoxPro" with "Access", "Word", "Excel" etc and ask yourself the same questions again. Desktop applications are not cluster-aware. Some server products are. eg SQL Server 2000, Exchange 2000/2003. Attempting to make a desktop application cluster-aware seems to be a major step in the wrong direction. Your initial instincts were correct. Now you just need to point out the differences between cluster-aware applications and non-cluster-aware applications to your management

If management want high availability with their database platform switch from FoxPro to SQL Server 2000 EE (on a MCS cluster). There is no such thing as a cheap highly available solution in the database space (well I've not seen one yet).
