This is a question/suggestion -- since a native Linux Ravenna implementation already exists in the form of the HAPI/HORUS firmware, would it be very hard to create a desktop client that speaks to pulseaudio and/or jack(d)? I can think of many scenarios, where such a thing would be very welcome, a of lot electronically composed and performed music (especially in the fields of live electronics, algorithmic composition and related research) is done on Linux.
Being able to directly connect a Linux system to a Ravenna router/network would be tremendously empowering and allow penetration of the technology into new areas.
