2. I really think that if we go via the j2ee route we need to delegate as much 
as possible to the bean as if the bean can be installed remotely when we 
resolve the issue of the non serializable objects.

3. Each service should have its own extension manager, we wrote it detached 
from engine code so that this will be possible... the notification service was 
one of the strong candidates...

> i saw these two constants are used at ExtensionProxy, which is not the bean
the extension proxy should live within the bean as well, so it can share the 
local constants.
