Unfortunately the Blackberry messaging services work via a PIN. Each and every Blackberry has a unique PIN which allows it to be identified by the BBM service. The PIN cannot be changed.So getting an non-Blackberry device (a device with out a BB PIN) to talk to the BBM is not possible.
Also since the Blackberry OS is closed source, as opposed to Android which is open source, the chances of getting BB OS ported to any non RIM device are remote in the extreme.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
