[Zope] is it possible to see whether any user is using a perticular zope object

hello , I am subrahmanyan. I am using zope for my project. Now I would like to know is it possible to know if any body is using the zope object. I mean , if one user is running one DTML method , I want to know that one user is using that object. Is there any DTML tag for that. thanks. bye yours, K.H.Subrahmanyan ( subrahmanyan.kalathur@wipro.com )
