In my case, ~60 ASLO's activities:
* Speak(and Memorize since it has Speak's code)
* olpcgames(FoodForce2, story-builder, falabracman, Maze)

Not sure about 0.86(we need, at least, fix existed activities) and
I'm not sure at all about activities that are out of ASLO.

Thats a good idea anyway, policies for inclusion/exclusion components
from/to SP, so we have first precedent..

In case if have numpy in Pippy, in my mind it doesn't make much sense in
having two Pippies:
* developers(and experienced users) are aware of such things(and they don't
need Pyppy installed from packages - in most cases they don't use
Pippy at all or use git repo).
* end users, in most cases, will use sugar-platform meta package thus
will have numpy anyway
