Well, distributing the verification "back" would be nice, but it seems to me (from your post and elsewhere) that there are practical issues with that (and little to no impetus for pools AND for-profit miners* to adopt such a technology).

In the end, though, all is better than it could be - we could have had just 3 pools, and we have more. We have ASIC first-mover who is very much into decentralizing mining. I'd say all turns out fairly luckily for BTC.
