sshfs more like NFS (or vice-versa)

[Andre Majorel <aym-naibed@teaser.fr>]

Are there any alternatives to sshfs that offer proper multi-user
support ? By which I mean letting user alice@client access a
remote file system as both bob@server and (by using sudo on
client) root@server.

Of course there is NFS over SSH but then some configuration is
needed on the server and being free from that is what makes
sshfs so attractive.

Thanks in advance.
