That's what I did in the early versions of m-o-o-t, except the OS was
OpenBSD-based. 

I could improve on that, maybe do a Linux/Knoppix version, but it still
would not drive some hardware, and it would still not be what the user was
used to.

In order to include the real luser newbies, it occurred to me that it might
be good to just let them use their ordinary setups, with just a few extra
programs and tweaks. New GUI background so he knows where he is, a slightly
different mail program, and _no unintended writes_. Intended writes go to a
SFS on a USB stick.



It's just brainstorming at the moment. I am considering completely changing
the form m-o-o-t will take.

I have a "bootable" USB stick, which is giving me all sorts of ideas too.

Had a quick look, will look some more.
