AppControlDelegate ? (just an idea. you may ignore)

Done.

pure virtual?

[Mr4D (OOO till 08-26), 2014/08/19 14:21:10]

Done.

Probably not your fault, but comment and the method name doesn't match :). Since
we're using app_id in the athena/content, it may be better to use
GetApplicationId() ?

Done.
