Transparency is not a goal of PB.

It does sound like you don't really need many callbacks though: your 
example code could be something like:

o = remoteThingy.getMeAVobContainer().addCallback(gotMeAVobContainer)

class RemoteVOB:
     def __init__(self, vc, tag, site):
         self.vc = vc
         self.tag = tag
         self.site = site

     def make(self):
         return self.vc.callRemote("makeVOB", self.tag, self.site)
     def export(self, s):
         return self.vc.callRemote("exportVOB", self.tag, self.site, s)
     def import(self):
         return self.vc.callRemote("importVOB", self.tag, self.site)

def gotMeAVobContainer(vc):
     for tag in vobs:
         v = RemoteVOB(vc, tag, start_site)
         v.make()
         for s in sites:
             v.export(s)
             rv = RemoteVOB(tag, s)
             rv.import()

Does that explain anything?
