Well, Libevent is only a library that provides compatibility across
different operating systems' asynchronous IO facilities.  As such, it
is basically never *required* for a new project; you could always
replace it with direct calls to the underlying OS facilities.  Since
FUSE is Linux-only, you could probably just write your networking code
to use epoll or aio and forget about portability layers.

As for the question of whether you *should* or *could* use Libevent in
implementing a user-space filesystem... I don't know why you couldn't.
 You can get an intro to what libevent can do for you at
http://www.wangafu.net/~nickm/libevent-book/  .  Only you can decide
whether that functionality is a good fit for your program, though.
