This probably doesn't go here, but I don't know where else it should be.

I was reading another thread here talking about RMSDK used by Kobo to render Epubs not handling various things (like smallcaps). Is there some resource somewhere talking about what all the existing hardware ereaders use to render Epubs? Do they all use RMSDK? All the same version? I can find nothing talking about the versions of RMSDK (or alternatives?) are available or why Kobo chose the one(s?) it did.

I also wonder if Wipro's acquisition of Adobe's ereader stuff like RMSDK will/has make/made any difference.
