Minor point - to do with trusting the code. Standard open libraries  
are trusted - what is to say that the Transcript code generating the  
SHA-1 hash has not been subtly altered? What is the best way to  
ensure this does not happen? An SHA-3 hash of the SHA-1 code :)

Yes it would be cool - not really sure if in the case of SSL it is  
better for the trust reasons hinted at above to keep the standard  
open external or integrate into the engine proprietary code.
