A couple of things I learned to while talking with a kscape engineer.
1) They do not plan an upgrade path from Premier to Encore. They are recommending you keep the Premier and operate it along side you Encore solution.
2) The disc server is different than the disk vault. The discs stored in the disc server are not ripped to the Terra server, but instead or played directly from the disc server. Therefor you can play ONLY one title at a time for discs in the disc server.
3) The Terra server does NOT have any protection (e.g. if you lose a drive, while the content on the other drives will not be impacted, the content on the failed drive must be re-downloaded (will be done automatically is my understanding), but at 50 or even 100 mbits downloading will take ~ 7 days with assuming full throughput at 100 mbits). My comment to them is this is totally unrealistic.
4) I was surprised they are only running a single 1gb Ethernet connection for the Terra Server.
Overall was impressed with the product, but in my opinion they have taken a few steps back, especially with no protection against data loss on the Terra Server.
