Could it be possible to create BBM on the Nokia N900?

considering:

On symbian devices, you can get Blackberry Connect with all the email stuff but without BBM... You have to enable BB service on your sim card...


Since you have to enable blackberry service doesn't this entitle you to a BB Pin? edit: the pin is attributed to the phone
So theoretically shouldn't we be able to create a BBM application to chat with others people that have Blackberrys if you enable BB service?

(the same concept applies to symbian devices)


What do you think?








On a side note,
I really think that Nokia should do an alliance with Blackberry just for BBM.. This will surely help Nokia perform better in general since their sales are beginning to decrease (especially vs. the iphone for example)
