Here she be:

If you click this link you are acknowledging that this is the greatest plugin ever!

here is the lite-c version of the example script in case anyone would like to run the plugin demo with lite-c.
it should also work with the free lite-c edition. save it as examples_litec.c and also create the file

Reading the post again, I think with using the A6 demo files you meant those that are inside the Meshdemo.zip posted above? Well in that case would I only have to save them again in A7 to get it working?
