Displaying multiple referenced nodes' fields through Views, using Views Slideshow
I don't know if it's possible to do this with views_slideshow but I just created a patch for the field_slideshow module. It will be committed once I have tested it a little more or there is some feedback.

The Field Slideshow module page.

The issue with the patch.

And the documentation page: drupal.org/node/1495622

So once you have installed the dependancies and libraries here is how to download and apply the patch:

git clone --recursive --branch 7.x-1.x http://git.drupal.org/project/field_slideshow.git
cd field_slideshow 
wget http://drupal.org/files/entity_reference_support-1634412-3.patch
git apply entity_reference_support-1634412-3.patch


Then enable the module and go to your content type display setting page ( something like admin/structure/types/manage/article/display ). Here you should be able to define the format of the reference field to be a slideshow.
