Alexander, I don't know if this is the missing magic, but compare your
code to the the code Chris Browne posted:

Chris Browne:
subscribe set (id=1, provider=1, receiver=2, forward=yes);
sync(id=1);    # Submits a SYNC event
wait for event (origin=all, confirmed=2, wait on=1);   # Waits for
that event to be confirmed on node #2

First notice that the WAIT FOR EVENT after the SUBSCRIBE is useless.
It tells you nothing. Second, notice the "origin=all" and "wait on=1"
in the WAIT FOR EVENT after the SYNC. Perhaps these are important
ingredients?
