@zooko, this thread is already overloaded and overlong; can we please conduct the renewed discussion of coin-weighted voted in a separate thread (whether a new one, or continuing one of the dedicated existing ones)?
Also (and pertinently to this thread): we have a tight schedule. The Helios vote will close on Jan 27th 28th, and hopefully things will then move very quickly towards implementation. So a new coin-weighted signal, introduced this late in the game, will either have inadequate time to crystallize, communicate and execute (presumably it would require people to pull funds out of their cold wallets and suchlike), and/or it may delay the overall process.
