Any mastodonians have an #ebookServer or #documentServer solution they'd care to share?

And yes, the irony of asking this on a WWW service has occured....

Probably involving HTML, but also capable of talking to eBook readers such as #Kobo, or software such as #PocketBook or #FBReader. Should have bibliographic metadata, and serve PDF, ePub, mobi, djvu, and other formats. Possibly on demand.

Bonus for #OpenWRT solutions.
