If I understand what you are trying to accomplish (of which I am not 
completely sure)...then you could create a script that accesses the object 
and returns a value based on the user agent string:

eg.

import string
REQUEST = container.REQUEST

targetObject = context.restrictedTraverse('/some/path/objId')

if string.find(REQUEST['HTTP_USER_AGENT'], 'Firefox') != -1:
   <do something with targetObject.attribute for Firefox users)
elif string.find(REQUEST['HTTP_USER_AGENT'], 'MSIE') != -1:
   <do something with targetObject.attribute for Internet Explorer users)
else:
   <do something with targetObject.attribute for xxx users)

Note: 'attribute' is whatever property you have defined for the object.
