I'm thinking (since the head of Kik was a former RIM employee, and he might have even been on the BBMessenger development team -- I can't recall exactly, so I don't want to impugn him), that there must have been some proprietary piece of a RIM patent used in Kik for the push delivery or instant communication Kik was good at.

But, I really don't know. All that is guessing and putting together little puzzle pieces I have read here and there.
