Email response from Krzysztof Siewicz, Licensing and Compliance Manager, Free Software Foundation:
"I confirmed with the management that the FSF can hold the registration and we are happy to hold it for GNU LilyPond. Would it be possible for you to complete the registration in the FSF's name?" I did so. The MIDI Association's website said, "You will be receiving your SysEx ID once generated (typically less than a week)." -- Karlin High Missouri, USA
