Thanks for writing this up. Putting the progress, ongoing work and plans related
to scaling in context, in one place, was badly needed.

Sounds good to me.
There are multiple ways to get involved in ongoing work, where the community
can help to make this happen sooner:
- Review the versionbits BIP https://github.com/bitcoin/bips/blob/master/bip-0009.mediawiki:
- Compare and test with implementation: https://github.com/bitcoin/bitcoin/pull/6816
- Review CSV BIPs (BIP68 https://github.com/bitcoin/bips/blob/master/bip-0068.mediawiki /
- Compare and test implementation:
https://github.com/bitcoin/bitcoin/pull/6564 BIP-112: Mempool-only CHECKSEQUENCEVERIFY
https://github.com/bitcoin/bitcoin/pull/6312 BIP-68: Mempool-only sequence number constraint verification
https://github.com/bitcoin/bitcoin/pull/7184 [WIP] Implement SequenceLocks functions for BIP 68
- Segwit BIP is being written, but has not yet been published.
- Gregory linked to an implementation but as he mentions it is not completely
finished yet. ETA for a Segwit testnet is later this month, then you can test as well.
