Currently S1 doesn't support data management on RAID arrays and/or a networked RAID array server. You can record, but you can't delete unused takes without moving the song to the local workstation, making changes, and then back to the server. Also I've seen some strange behavior with events referencing the wrong audio...
Many people may not need this, or see this as important, however anyone who would like to see S1 gain a larger foothold in multiroom commercial facilities should consider voting for this.
