Still, this is the wrong assumption.  JB is right that Shannon's theory 
is only meaningful when there is a context.
The same bit can mean different things in different context.  The 
implication of your suggestion is that we can assign every possible 
states a bit pattern. But if cap the size, the implication is that web 
is closed.  If you don't, then the problem comes back to you.
