Agenda: decide a unique name for the second part of Metropolis

[axic]

Would be nice to make a decision on the "Hardfork meta EIPs" (and potentially merge them):

• Add meta EIP for hard forks EIPs#233
• Add meta EIP for Spurious Dragon EIPs#607
• Add meta EIP for Tangerine Whistle (EIP 150 Hard Fork) EIPs#608
• Add meta EIP for Metropolis/Byzantium EIPs#609
• add table of HF meta-EIPs EIPs#676

[axic]

If time allows would be happy to receive comments on ethereum/EIPs#663 and ethereum/EIPs#215.

Proposed names for Metropolis:
First HF - Byzantium
Second HF - Constantinople

Nick/Vitalik working on EIP 96, 98, and addressing concerns with gas scheduling in 198.
96 Nick working on tests
98 Intermediate state root removal - no gas stuff figured out
198 - main thing to still be figured out, suggested on a few days ago. piecewise quadratic
Martin/Arkiday work on benchmarks.
EIP for miner reward reduction needs to be officially combined with ethereum/EIPs#669.
Put ice age changes in #669.
