Hmmmm....still doesn't work. I added

;@WORK kftpd_password=test
;@WORK khttpd_files=0

under the [Network] section of the config.ini file. I synchronized, then I went to the Hijack menu, selected ;@WORK, and rebooted. Using the windows default command-line ftp program, I connected to my Empeg (which has a fixed IP, btw). It prompted me for a login name, at which point I could do anything, including just hit the enter key, and it connected to the filesystem. Any ideas? Where should I put the ;@HOME and ;@WORK lines, anyway?

One other aside: redefining KnobLeft and KnobRight prevents you from navigating the Hijack menus using the knob.
