SSHFS

This looks like something that could be useful. Looks like it is easier to set up than NFS or SAMBA, maintains a secure connection over SSL, and is cross-platform compatible (though could be tricky with Windows). I've always wrestled with getting SMB to work correctly at home, there are just so many configurable options, and I've never really taken the time to sit down and learn what all can be accomplished. Maybe that'll be a future blog post...

I'll have to put this on my Gentoo box when I get home to test it out with a Ubuntu VM. The challenge will be figuring out how to script it to use keys instead of passwords so it automatically starts every time the OS starts, although LinuxJournal seems to have a nice tutorial on how to do this.
