Best way to mount a Linux filesystem on Windows over the Internet?

I was going to attempt Samba over SSH, any better ideas?

Edit:My mom has been bugging me to do some offsite backing up of her files. She currently uses Norton Ghost. I have a VPS that I use for some other stuff and I figured that I could just setup a FTP server and let Norton connect to that for some offsite backing up action. But for some unknown reason, Norton doesn't handle SFTP or FTPS, so I have to figure out how to automatically mount a Linux drive on Windows or get Norton working with SFTP.

Edit:Thanks for all your help guys (girls?)!
