Ok, I did a quick search and it appears the failover function is supported by dot net so I would recommend you take a look at this method in the mmDatabaseManager class. You can override that and add support so the failover is added to the connection string:

public virtual string GetConnectionString(string databaseSetKey, string databaseKey)

This method just retrieves the connection info from the configuration file and builds a standard Dot Net connections string. You could pretty easily add what you needed to support the failover function I would think.

Alternatively you could more easily override an AbusinessObject method to alter the connection string once it is retrieved and set on the dao but before it is used. This would probably mean using a setting somewhere that gave you what you needed for the failover connections string info. I would have to look further to figure out the best place. If you need help with that, let me know.
