(and a few other alts whose names I forget) Right now the shortest path to adoption would be to release a v0.12 with just a CLTV soft-fork as soon as the BIP66 softfork triggers. While there's been proposal to change the way the upgrade mechanism triggers to a multiple parallel fork scheme, that is quite complex, stateful, and will need lots of review, probably a few months worth; faster would be to continue with the existing mechanism. IMO the main reason to accelerate CLTV is scalability. The only viable scalability improvements possible in the short/medium term that don't entirely rely on trusting third parties are payment channel based. While we have a working payment channel scheme - Jeremy Spilman's refund tx based system - it is fairly complex, needs good and immediate backups, and is susceptible to tx malleability. CLTV fixes those issues robustly. Of course, payment channel schemes can start off with Spilman's scheme first and go to CLTV later, but that is a lot of extra code to be written and later depreciated - I'm sure many authors are dubious about going down that path. Thoughts?
