[Sorry to resurrect this, but I have a kooky idea. I have no illusions about 
implementing it, it's more intended to nail down my understanding of this 

Is it possible that the problem with this discussion is that everyone 
assumes some sort of fixed obfuscation algorithm in the m0n0wall sources? 
Instead, couldn't an installed m0n0wall store a secret key that is
notincluded in the
config.xml file? The secret would be set from the physical console menu, and 
stored elsewhere in the installed m0n0wall image.

Whenever DynDNS or PPP or anything else needs a password, the local secret 
key would be used to decrypt (in memory only) the appropriate config.xmlentry.

As I said, it's a kooky idea and probably breaks a bunch of design goals, 
but would it work?
