Whom could I encourage to realize such a project?

Tools like privatix (see http://www.mandalka.name/privatix/index.html.en )
are designed for MOBILE use to make internet cafes a SAFER place. This
does not mean such systems offer perfect security.
Booting your own OS safes you from "software attacks" like the ones
Heinz Diehl mentioned (is this right?). Thus the "only" remaining thread
comes from the hardware side. It seems to me the most COMMON thread there
are hardware keyloggers. I thinks hardware based video-grabbers are not
that common (what do you think?). They need a lot of disk space, don't they?
In my scenario the attacker would need a hardware video-grabbers AND a
hardware keylogger, I think this should be unlikely in common internet cafes,
while a keyloger alone is likely.
HD camera pointed at the screen don't seem such a threat to me since in
internet cafes you can often turn the screen or move your body close to it,
so its content is hard to see for others.
My point is I want to be protected agains the likely threads, not the unlikely.
If I have very very sensitive data, I agree, that using an internet cafe is
no good.
Originally I was looking for a rather safe way to use my gnuPG-key in
internet cafes or foreign computers.
