I, along with qqwref and ben1996123, have started a collab solve of a 256x256 Rubik's cube. We're expecting a few more participants to help with the solving effort.

We expect the attempt to take anywhere between 100 and 110 hours' solve time, which could mean up to a month's worth of sessions in real time.

As for the method, we'll be using a variation of the cage method for this solve. Roughly outlined, the steps are:
1) Clearing the 1st/green center - Partially filling in columns of green pieces
2) Solving the remainder of the green center using the 4-move commutator r u' r' u
3) Clearing the 2nd/blue center - Partially filling in columns of blue pieces
4) Solving the remainder of the blue center using the 4-move commutator r2 u' r2 u
5) Solving the outer shell - edges and 3x3
6) Clearing the 3rd/orange center - Partially filling in columns of orange pieces
7) Solving the remainder of the orange center using the 4-move commutator r2 u' r2 u
8) Solving the 4th/yellow center
9) Solving the last two (red + white) centers

I've started the first bit of the solve. Progress so far, at just over 2 hours into the solve:

lol the idea of this tickles my fancy
just how are you going to collab solve? I don't have the patience for this kinda thing

How are you gonna collab on this? I would love to join, if this is still a thing.

Not being familiar with ultra-big cube strategies, what is meant by 'cleaning'? From the image it's obviously denoting the change from a totally jumbled face to the obviously green face; how is the 'static' left behind determined, aka is the solver initially drawing from only four other faces or is something else the cause?

The cleaning step = partially solving the center columns using nU/nU2/nU' moves to draw in pieces from the middle ring of faces, roughly as follows:
