1- Yes. The emulator, however, doesn't emulate USB, so UMS can't work in the emulator.
2 - All devices which have the correct partitions have UMS. Devices like the Nexus 4 or 5 don't support UMS. I'm pretty sure that all of the shipping devices have UMS support. 3 - We use the vold service from android. The AutoMounter (found in dom/system/gonk) communicates with vold to manage mounting/unmounting/sharing etc. UMS requires partitions which are formatted using the VFAT file system in order to create sharable internal storage. External sdcards also need to be formatted using VFAT (this is how they typically come when you buy them).
