That's due to the MIDI clock being sent/transmitted (http://midi.teragonaudio.com/tech/midispec/clock.htm), which MobileSheets already supports. That is completely separate from something like the BeatBuddy that requires the tempo to be set through a control change message. The BeatBuddy can already be controlled through the MIDI timing clock feature in MobileSheets if you change the metronome tempo. It just won't be as accurate as specifically setting the tempo you want (as there can be small variations depending on the type of device you have).
