OK, rather clever Todd!! The only thing you lose is the ability to have your users log in with their own account and keep their images separate, allow their own delivery folder/naming, etc. if I understand you. Your web UI is running with full access to the entire computer as it thinks you are in the observatory. Data goes into the "real My Documents or via the Observatory Operator's file/folder renaming templates. That's why it won't ask you to log into ACP.
