Remember that geohot's cfw was set so that it would not allow piracy, and yet it was made to do so by someone else i believe.
So first of all, just because kakaroto's software may not allow piracy, someone else may be able to mod it.
Second, even though geohot's firmware did not allow anything illegal, we saw just how badly sony wanted to stop him. sony may find a way to get to kakaroto even if he is in canada.
and third, he's off on holiday for the next 2 weeks so dont expect anything soon.
