Just as a follow up to my request to look into syncing between Kobo ereaders and the Moon Reader Pro Android app, the developer of Moon Reader got back to me with the following:
hi, there's no standard for Epub reading progress or highlights yet, so the reader can't share its reading state to other readers.
Thank you!

I don't know enough to know whether that's technically accurate (Moon Reader can sync pages between multiple Android devices running the program), but I take it, at minimum, as a very polite "I'm not really interested."
Oh well. No harm in asking....(at least I don't think there is
)
