I tried buying into this, got burned. Dell XPS Dev Edition, top of the line Dell Thunderbolt Dock, should work great, I thought. Nothing but trouble, tons of complaints online, Dell refused a refund as it's "not defective" - it just doesn't work with Ubuntu well. The OS preinstalled on _their_ hardware. Most of the complaints about the Dell Thunderbolt docks are from Windows users, to top it all off. My point being that the scenario you envision is now being sold by some manufacturers, but not necessarily delivered. These docks also have their own firmware, sometimes _multiple_ different firmwares, and at least those I've tried only let you update via Windows. There's UEFI updates that are supposed to help as well, again only updatable via Windows. So far, I can't say I'm super impressed with the reality of non-Mac Thunderbolt.
