With the High Availability license it would be handy to have an automatic replication for a scripts directory on a scheduled sync basis. While that's easy enough to setup the HA system should be checking to make sure both members of a pool are identical.
This way by pre-specifying where any scripts live and then having the HA system handle that replication as well would be a nice out of box experience to ensure if a failover event occurs, any scripts would still trigger.
