Also, looks like sshfs used in Slackware is abandoned.

A quote from the link, I wonder if this project will be the 'one':
>If you would like to take over this project, you are welcome to do so. Please fork it and develop the fork for a while. Once there has been 6 months of reasonable activity, please contact Nikolaus@rath.org and I'll be happy to give you ownership of this repository or replace with a pointer to the fork.
I also wonder if it was abandoned due to the RHEL re-orgs like what happened to bluetooth.
