Smith hacks himself into the body of Bane which is the first step he took for destroying Neo in the real world and also because the Oracle says he would eventually get into the real world. (That is what I recall anyway, please correct this if I am wrong)
My question is, how would have have done this? Smith gets into the real world, Zion. He plans on killing everyone and in the Matrix, he changes everyone to Smiths.
Would he have just hacked into those jacked into the Matrix continually?
