Get Variable - Flash Comand

Is there actually any way to communicate a simple variable from a flash SWF movie into Lectora? This should be very basic functionality, and it's very simple as described in the documentation. Is there a reason "Get Variable" doesn't work? 

Also could not get my flash movie to fire commands in Lectora's API, as suggested as a duct-tape workaround in this thread. Is this API accessible to programmers, so that we may interface with it, or is it a secret?

We're considering Lectora to author a large amount of training material, but basic required functionality that is sketchy in it's implementation makes Lectora a difficult technology choice to justify.

Any ideas?
