MIDI manufacturer ID

Nicolas Joyard proposes adding sequencer-specific MIDI events to enable 
point-and-click interoperation with players like Frescobaldi.

One parameter of these events is a registered manufacturer ID, which 
leads to this discussion:

There is a one-time fee which is small enough not to be a barrier.

Is there an ideal person to contact the MIDI Association and ask about 
getting an ID?  (I don't want to be in the loop.)  I would expect some 
discussion about which person or organization will be licensed to use 
the ID.
