For what it's worth, I have fuse-sshfs installed on my SME 8 server, but I do *not* have 'smeserver-fuse' installed.
I have no notes on what I did - which either indicates that it was too simple to bother documenting, or I was in too much of a rush to create any documentation.
Install may be as simple as
configuring the dag repo for SME 8 then installing fuse-sshfs using:
yum --enablerepo=dag install fuse-sshfs
