> signature recipient that the data was constructed by an unforgeable,
> cryptographically identified software stack.

>   c. Sealed storage. The ability to securely store information so

> components that can be identified in a cryptographically secure
> manner.

>   d. Secure input and output. A secure path from the keyboard and
> mouse to "Palladium" applications, and a secure path from "Palladium"
> applications to an identifiable region of the screen.

1) Does anyone but me think this will be used for digital media copy 
protection more than anything else?  I could be off with this one, but it 
sure smells like it to me.

2) It humors me to see them take such esoteric measures when the design of 
almost every piece of software they've written to date has thown security out 
the door in the name of ease of use, and thorough software infrastructure in 
the name of virtual paper clips.
