Offline Transcoding

Hi there.
I had an idea if offline transcoding wouldn't be a nice optional feature.
I basically would rebuild my database or a part of it with the data format as accepted by the TV.
And safe it on a separate drive.
That might more efficient then transcoding all the stuff in realtime over and over again.
Low power servers wouldn't suffer anymore from transcoding stress.
And powerconsumption would probably go done as well as HDD wear down.
Obviously things get complicated if your run more then one device.
What do you think?
Cheers
