Currently the only absolute object id, is the objects path. Which you 
can get as:

    theObjectPath = object.getPhysicalPath()[1:], '/'

If you then want to get the object you can use:

    obj = self.getPhysicalRoot().restrictedTraverse(theObjectPath)

In fact they are identified by their full path.

You could also check out the "mxmRelations" product which will do a lot 
of the grunt work for you:
