> What was the motivation for building it this way, instead of by more directly exposing PCIe?
I think when intel was doing Light Peak, they didn't have IOMMU, which in my limited knowledge seems to be a solution to at least some of what is wrong with normal hot plugging PCIe (aside from somewhat complicated hardware design, I imagine). Of course IOMMU was clearly never implemented correctly, so all was for naught.
