How much does a permitted word list shrink the key space?
How large is the data set that would be the permitted word set?
What user interaction would be involved if a word was not in the
permitted word list?

The most likely phrases?:
#1)  The quick brown fox jumped over the lazy dog
#2)  Double double toil and trouble fire burn and caldron bubble.

I fear that what looks like a modern stronger key system will
be system dependant and invite trust ... yes we already have internet
companies
that keep passwords in clear text. We also have companies that prune the
characters to the first eight and ignore the next 500.

CaMel case?

BTW: I like the basic idea.

$ wc /etc/dictionaries-common/words
102401 102401 972398 /etc/dictionaries-common/words
