There are two types of ownerships
- the user who created the object.
    It limits the maximum rigths the object can muster when it is 
executed (hence it's name)
    It can be changed with a method as follows
- a user that has assigned the role owner
    Such a user can assume owner rights when dealing with the object

So what you need to do, is create an external method that sports an 
method like the one that follows.
This external method you call from a python script with the appropriate 
parameters.
That this script is allowed to do its duty, it must have assigned a 
proxy role of admin. you can do so clicking on the scripts tab proxy.
