IMHO, releasing it with a couple of working examples would be sufficient to get the ball rolling for most of the hacker types who would be interested in working with the prototype.

As the code is C# based, Visual Studio Express would provide the perfect vehicle for experimentation, requiring little in the way of formal packaging.

Release it under Github and let the organic evolutionary forking work.

I would expect there to be a flurry of prototyping activity, which should be culled into a stable release once this phase settles.

I would recommend to get the ball rolling now before the conference in October so that it can be released then.
