I stumbled across this while messing with debian's apt-cache search. kio_fish is a KDE extension that provides a way to browse a remote directory usingssh. There is no need to setup an FTP or web server on the remote system as long as you have an account there. Just point konqueror to fish://firstname.lastname@example.org.
BTW, depending on your KDE installation, you may need to also install liblcms
