They're first a global resource - the file exist everywhere.  The only
think that makes it per-user is how ncftp interprets them.  By looking
into looking into /tmp/$SID/ncftp/bookmarks it could be made per-session.
(although that'd be totally useless of course)

It's very much a technical/philosophical question.  The user interface
isn't a thing that just happens out of thin air, there must be an
implementation behind it.

And in UNIX our traditional model for this kinds of things is to be per-
session, initialized by per-user values.  At this point we have an user
interface, and it's a well-understood one that works very well for similar
things.
