I salute the recent progress on the Dagger/Hashimoto, but it seems there is no commitment yet to it.
Q1: When should we expect the selection of the PoW algorithm be official? Q2: Will the PoW implementation be part of the security audit?
Obviously, the mining aspect of Ethereum will receive a lot of visibility on the genesis day... yet the PoW algo is still not implemented and the community has less than 4 months left to play with it.
There is also all the aspect of the difficulty adjustment that is still unknown. This will likely require tweaking prior to the genesis. I understand that there is plan for in-house stress test, but I believe there is value to expose the algo to "random" test driven by the community over a significant amount of time.
