A cool video about a ­frame­ featuring 2 rear airshocks, seems like a realistic pipe dream to me.

wow, seems like a very smart idea to me, but most shocks now act as 2 with all the adjustments they have for example my dhx5 with the ti spring is extremely plush at the bottom of the stroke to absorb all those small bumps and then i have 150psi in my boost valve and so when i turn my bottom out control all the way up it feels alot stiffer, top DH bikes today like the v-10, m3, m6 etc. use these shock adjustment to very most, if you ever look how they work they work just the same as this one but are much lighter because they have one shock that can do double the work and do it much better.

doesnt the corsair crown DH have two shocks?

yes in did!
