Anyone know of something like this, but integrated in a USB cable? http://www.mini-box.com/Y-PWR-Hot-Swap-Load-Sharing-Controller …
Usage case would be moving a USB-powered device from one power source to another without interrupting it.

Could one of those dual-USB-A to mini-B cables for powering disks do the job?

Yes, but they lack reverse current protection so it seems like bad things could happen if voltage mismatches.

I probably don't want an over-voltage USB battery pack running current back into my laptop...
