how do you use it with adbapi ?? I mean, how do you use callbacks with your
flow ?

How does it work if a bloc has several inputs ?
I want to do this :

DS1 ---> FS1 ---+
                +--->  FS3
DS2 ---> FS2 ------->  FS3

Two datasources provide some data. Data are used to run Fuzzy Inference 
Systems (FS1, FS2, FS3).

FS3 must wait until all its inputs are ready. Is it possible with flow.py ?
Will it be possible ?
