Might such a function be useful to salvage the (non-functioni= ng) network? Same for IRC bootstrapping. How do we pick ourselves up off t= he ground in case of the equivalent of a great depression in network hash r= ate (or some jerk spending $100M just to drive the difficulty up and then t= urning his hardware off?). [Aside: When replying to the digest, please try to trim it] It appears that we will soon be at a hashrate where all the desktop CPUs in the world couldn't really make a dent in it... certainly not desktop cpus using the slow integrated cpu miner, which is much slower than external optimized cpu miners. But this is why I suggest packaging up a modern mining tool that supports CPU/GPU/FPGA/ASIC mining against a current bitcoind. Doing so would reduce the difference between testnet and mainnet, and provide an actually useful tool for contributing directly. Though again, I note, that Jeff's patch doesn't actually remove the integrated miner (I think it should=E2=80=A6). Just the getwork support fo= r external miners which don't use getblocktemplate... and if you're going to download one of those you could go download bfgminer instead.
