That doesn't explain WHY identical twins will be quite different (sometimes even mirrored - those are weird).

Identical twins are always mirrored. If the zygote splits early enough, at just a few cells, there is almost nothing to mirror. In a mathmatical sense the zygote has more axis of symmetry at that time. If there are several cells in the zygote when it splits then the mirror effect will be more pronouned. All twins and placenta have a differnet placement in the womb and this can effect their nourishment.

Nature would seem to be likely to produce analog systems with resonant feedback mechanisms rather than systems that run binary and open loop with simple smearing between generations

I'm not sure I understand what this sentence says. DNA follows a fairly simple algorythm, and the only "feedback" mechanism is that the processes which don't work are less likely to produce offspring.

Otherwise, we should be able to shear off all but those 10,000 codings and produce some much shorter chromosomes

The chromosomes of the father and the mother have to come close to matching for the sex exchange to work. If a father suddenly got a streamlined DNA then his chromosomes would not match up with an average mother. Sex tends to preserve DNA, and that includes both genes and junk.
