He he, I had forgotten all about this question, until the email popped up.
Anyway I have set up staging, and it has run nicely for 3 months now. Not without hickups but not with anymore than networker usually have.
The above guildelines are the way to go, and test it well before using in a production enviorment.
So far the only thing I have had really trouble with is when the staging does not clear all the savesets and try to stage again, this will fail with volume inellible use another, just check the SSID's there will be duplicates remove the duplicates from the filedevice and retry the operation.
