As much as I would love to work part-time, there's a good reason for a company to avoid this: co-ordination costs scale quadratically. Yes, good management practices can help mitigate this, but I'm sure we're all aware of how adding extra people to a team doesn't scale its productivity proportionally, and I'm convinced this is at least part of the picture.

That said, if the co-ordination costs are not prohibitive and such an arrangement allows you to get better talent than you'd otherwise have access to, it might still be a good deal. For a small team that needs a small amount of high-level expertise, but doesn't have enough for such a person to do all day, this could be the best option.
