Doesn't work that way. You can't send information faster than light.

Not in classical or relativistic physics you can't, but there are some questions in quantum physics.
Electrons do not move from one orbit to another of an atom, but disapear one place and appear instantaneously in another orbit. There are a nuumber of other quantum transitions that take place without passage of time.
Is information moved? That is the difficult quible.

Everything I have read about quantum entanglement suggests it cannot be the basis of faster than light communication.

At the very least it requires you to physically transport the entangled particles to the receiving destination. That pretty much rules out using it to meet alien civilizations.

from what little I have comprehended of what little I have read on the subject, the following is the (quite possibly incorrect impression of) property of entanglement which interests me:

2 entangled particles, separated by significant distance.
perturb one of the particles, and the other particle instantly undergoes the same perturbation.

if this is so, one can consider one state of perturbation a zero, and another state a one, thus creating a binary communicator allowing instantaneous -if absurdly simple- data transfer irrespective of distance.

again assuming all the above, and assuming the number of entangled particles can be jacked up to something more useful, then REAL instant datacomm is possible. the applications would of course include controlling long-range unmanned recon on Earth and (more importantly) in space... no more long waiting periods between command, execution, and reply - it'd become similar to actually being there in real-time, more like controlling an RC car on your lawn.

That'd be damn nifty... if it is indeed possible

The planetary model of electron behavior is not valid. It would be more accurate to say that electrons vibrate at one frequency, then suddenly without passage of time vibrate at a different frequency. There's no "movement" to another "orbit." There's no inconsistency.
