Maclen Marvit from Disappearing Inc. <http://www.disappearingink.com/>  
spoke at
a Cypherpunks meeting back in 1999.  There'd been a bit of press about  
them in
the previous weeks, so there was some skepticism about it, but he  
started by
making it very clear what problems he was trying to solve and what  
problems he
_wasn't_ trying to solve.  Stopping people from taking screenshots  
etc. was on
his not-trying-to-solve list, because any solution is pretty much  
snake oil.
Keeping your company's backup email server tapes from being subpoenaed  
in an
anti-trust case was in scope, and it looked like a reasonable  
solution, and any
company large enough to have lawyers has document retention and  
destruction
policies of some sort. (Keeping your company's _future_ emails from  
being
subpoenaed if a court orders Disappearing Inc. to retain your keys  
isn't a
technical problem, it's a lawyer problem, so it's also hard to solve.)

Ian Goldberg's Off The Record instant-messaging application is in a  
similar
space.  If the person you're IMing wants to save or divulge your  
conversations
or pipe his computer monitor into Tivo, it's hard to stop them, but if  
you want
to prevent your messages from leaking if your IM server is cracked,  
it'll work
fine.
