Disconnecting guests via a script

[pvision]

is it possible to disconnect guests via a script step?

I can set a file as Single User via a script, but if the file is shared the user gets a dialog box and the script pauses. I'd like to automate the disconnection of guests so that I can run a timed backup of the hosted file

Yes I know the client should be using Filemaker Server...
