I'm pretty sure my employer would come down on me if I did something like that - ereaders are a pretty small market, even if you don't personally work on anything remotely similar - but how hard could it be? Make a Raspberry Pi hat, stuff a Zero in, and you can probably get renders of pdf/epub/mobi/html/etc pages going fairly easily, to propagate to the display.
Well, maybe not a Pi Zero; the new versions come with wifi. But still.
Quite poor on features (does not support images or even chapter progress), but I've read many EPubs through it. Syncs books and position via Google Drive.
Does not work in Edge though, Microsoft could not fix a bug for a year (and still can't). https://developer.microsoft.com/en-us/microsoft-edge/platfor...
The beauty is you can add it as "app" on Android and/or iOS. And it works with desktop as well.
It's written in Go in macOS. So we have to cross compile it for different systems.
