Here's a feature request borne out of dealing with a downed router.
We were using the cdrom image with a floppy for saving config when the
floppy disk died.  The router seemed to work fine but the web interface
returned:

XML error: no m0n0wall object found

Unfortunately, this prevented me from retrieving any of the config.
Anyways, keeping a backup of config.xml in ram and making it
downloadable from this error page would have totally saved me.

Needless to say I spent the time to get m0n0 to boot off of a harddrive
this time around.

cheers
