Very interesting project, it's not my area, but it looks more like the program code is intertwined with the architecture of the quantum computer hardware.
Take for example this piece of code. It seems to define the registers and measure them, so this is more like writing quantum emulators, rather than programs. Right?
from qiskit import QuantumProgram
qp = QuantumProgram()
qr = qp.create_quantum_register('qr',2)
cr = qp.create_classical_register('cr',2)
qc = qp.create_circuit('Bell',[qr],[cr])
They are quantum programs. The bell state program you posted is not really enough to show how you would use this SDK. Here is a better example [0] that shows how intermediate quantum computers will be used to solve optimization problems.
