ok. i want to read on different devices for some reason. like a good book on the couch with a tablet, in the kitch looking up a manual on my phone and maybe working on computer read some magazine. that would mean i need to install 3 clients and maybe without nfs even have a copy of each book on each device? and if you jave nfs you could aswell run a calibre container somewhere. but for UI I agree web could be better.
