Have you solved this in the meantime? In general, your message doesn't contain nearly enough information for anyone to really help you: we don't know what Estimator::cell is, we don't know how you try to transfer data, we haven't seen your code, and we haven't seen the compiler's error messages. We could poke in the dark, but it would probably be more productive if you gave us a bit more detail explaining what doesn't work.
