Well, I guess I'd probably be interested too, I am getting a bit lazy in my old age.
Can it play several voices on one coil? I like that feature. My original interrupter had six pulse outputs, since the Roland synth I hacked up had six hardware oscillators. To play with fewer than six coils I just ORed the pulses together with diodes.
Is there any chance of releasing the source code so we can hack on it ourselves? As a coder myself I'll fully understand if you say no! But there are weird features that I'd like to have, such as a single shot button, and support for my driver board's remote DC bus voltage and fine tune adjustments.

Yes, it can play two voices per coil. I limited it to two because it tends to sound like total crap with more than two notes. However, I have coded this in such a way that I could add more voices per channel with minimal effort.
There is no chance of me releasing my code to the public (sorry). I don't even want to think about how many hours I've put into it. I started the project last May, and I've dedicated almost all my spare time to it.
That said, I would be willing to work with you to get new features integrated into the controller. I'm sure we could work something out. The beauty of this thing is that it can easily be upgraded at any time. You simply put an intel hex file on the SD card called fw.hex and you can reprogram the controller from the bootloader.

When it's in QCW/SSVC mode, do the other outputs give PWM for DC bus voltage modulation or something similar? That would pretty much do the job if it were available in DRSSTC mode too.

And, how much are you planning to sell it for?
I send numerical values (0-4095) across the fiber. The fiber terminates at another MCU which then translates the values into a voltage. Actually, I'm still working on that part. I figured that the QCW/SSVC mode would be of least interest to most people, so that's been given low priority.
As to the pricing... I don't have FIRM numbers yet. I'm hoping to have that nailed down soon. I'm going to try and make it "affordable" without killing myself in the process.

I must say that amateur electronics have come a long way when products like this comes out, very nice work indeed.
I fear for the day where I no longer can keep to doing single sided boards without smd :)
I fear the day when I can no longer see the SMD parts that I so frequently use! I guess at that time I'll have to pull out magnifying lenses. I nearly need a magnifying glass to assemble my RGBLED/TX boards.
Those little MOSFETs are a pain to solder up with an iron and solder wire. They were the main driving force behind me finally getting a hot air rework station and solder paste.
