This one is the BEST answer!

If pool A start pool B using a call activity you can define the data to pass from A to B and B to A in the call activity defined in pool A. Data will be sent from A to B when process A execution reach the call activity and instantiate process B. Data will be sent from B to A when process B execution finish.

If pool A send a message to pool B message can carry data and so allow you to pass information from A to B (and B to A if B send a message back to A).

If you have business variable of the same type declared in A and B, you can actually only exchange the id of the business variable as stored in the database. This allow to have both process actually working on a same copy of the data instead of duplicating it.

I built two examples, one with call activity, one with messages. Both are packaged in a single bos file:
