Version 3.1 supports OAM files as well.
Version 1.5 now supports Edge Animate HTML files in the Web Content Overlay of CS6:
Which is slightly easier than the embedded HTML solution in my previous answer. It also offers more control over starting the animation with a tap.
Then insert the following HTML code (or similar) into your InDesign document before exporting with in5:
<iframe width="400" height="400" src="edge/nameOfEdgeAnimateFile.html" frameborder="0" ></iframe>
We'll also look into the possibility of translating the OAM file into something that in5 can read. If you can upload a sample OAM and INDD file that would be helpful for testing.
Based on @topelovely's file below, I've created a sample page:
and Source files.
The trick is making sure the file path in the src attribute matches your output. For example, if the in5 index.html file had gone into an html5_output subfolder as it does by default the src attribute in the iframe should reflect that:
The double period (..) in a file path indicates one directory up.
