This is interesting. Work-from-home CS jobs aren't a new thing, but aren't widely deployed either. It can be tough to monitor remote workers, although phone calls have a lot of good metrics associated with them that are easier than some tasks. The rest are part-time warehouse positions, which are fine for what they are, but aren't breaking new ground just expanding what they already have.
I'd really love to see some more corporate knowledge worker roles be able to move part-time, though. I work for a good employer, my work is interesting, but I'd really just like to be at work in general a bit less. There's not a lot of market for a "freelance" project manager the same way a coder or designer might be able to pick up. I'd just like to work on half the number of projects, and take home less pay. I'd be happy to work 3 days a week for $60K and the low-tier health plan, instead of more than double that plus considerably more expensive benefits and matching etc.
