2 way communication between content in an IFrame and Storyline

Hi Jürgen, good question (and an interesting read).

There are no external links outside of the direct links to the Daughters themselves, which would all be contained within the published WebObjects folder of the 'Mother', each Daughter having its own subfolder.

The Mother and Daughters will, as one published package, either be hosted on an LMS in SCORM format, where the user has access to the secure hosted network or, in some cases, where there is no direct access to the secure network, the training, in HTML (published for Web) would be hosted locally on a desktop/laptop, so in both cases, unless I am mistaken, they would, under the "Same-origin policy" have come from a single origin.
