Again, if your ePub renderer does not implement Javascript support, any Javascript elements will be diregarded.

The other real difference is the that the webkit renderer Kobo uses for kepubs is an ePub3 renderer based on the Readium code which handles quite a bit more of the ePub3 specification than is handled by Adobe's newest ADE/RMSDK products.
Interesting. Thanks for the info. When I get a chance, I'll convert a few books to kepub to see what difference it makes on my Kobo. What is the adoption rate of kepub? Do you know?
