On my todo list:
- Bitcoin days destroyed (thanks Stephen for explaining)
- Solid coni support
- Complete the move to the bitcoind mysql backend and remove rpc polling
- list addresses with the highest balances
+1 to notion of adding the Bitcoin DD (days destroyed) stat.
One other comment: where do you get $1000 / 2 years for 1 GHash? Is that approximately 50% depreciation per year on a rig which costs $1/MHash/s? Don't disagree with the number so much as interested in how you derived it.
