[Kde-kiosk] Disallowing Multiple Opening of a Window

[steve f]

Is there something within KDe that will prevent me from starting more than 
one instance of an application?

I have an XTerm session that begins when you click an icon. Problem is, I 
can't have multiple windows opening of this application because every one 
you start takes another tty session on the server.  Is there anything in KDE 
that will limit to one running session of an application when the icon is 
clicked?
