 Yes but *they* don't, they just need accounts on a box with calibre
installed. I can run calibre on any machine I can log into which has it
installed and I can display it on any machine I can log into which has X
installed. I don't need root anywhere to do that. I can even install
calibre (or anything else) into my home directory without root.

 I can run *any* GUI application available on *any* machine I can log
into and display it on *any* suitably equipped machine I can log into
without troubling a sysadmin.

 You assume that I have sufficient control over the server to set up
exports, this is not always the case.

 Oh yes and then there is the little detail of ensuring that
everyone has the *same* userid on *all* the machines that may be used.

 Another point for you - when you export your calibre collection
by NFS you expose it to all the manipulations possible via the filesystem
not just those provided by the application.

 You supect very wrongly - I've never owned an MS Windows license
and I have been developing software on unix systems since the early 1980s.
FWIW it irritates me that I need to use a GUI with calibre but the command
line usage is impossibly clumsy for anything but the simplest of tasks.
