Stephen,

Stephen, restate your duality theory, in 100 words or less,
then I will comment. :-]

100 words, not 1029 words (yes I counted them)!!!

[WDE]
I suspect that the entropy (S) of U^U is k*U or { U * log(U) } ???
And that the probability of being found in u_i is:
P_i = u_i / (U^U) ??? So that,
S = U * log(U) = sum{ -P_i * log(P_i) : i = 1, infinity} ???

When you can say this in 100 words or less, then you will know whether
you are right (consistent) or wrong (inconsistent).

I think of your bisimulation as being more analogous to interference
than to interaction.

[WDE]
Sounds good to me...except that I prefer "bisimulate (read "INTERFERE with")"
