Thanks for this Peter. It is quite long winded and complicated so I just wanted to clarify one particular point. In John's proposal, are the coins actually locked up, or are they still freely spendable post-vote? Otherwise there is no real cost to casting votes. Locking coins up is related to the time-value of money and has a cost the longer they are locked up for.

Yes, John Dillon proposed a very clever and viable blocksize vote scheme on this list awhile back: https://www.mail-archive.com/bitcoin-development@lists.sourceforge.net/msg02323.html
