Basically, in order for us to take the DelphiX torch and keep on running, we're going to need Hori's permission to Open Source it.

What Hori's saying is DelphiX is Free and you're free to make anything using it, but the source is his as are the samples. So no repackaging, redistributing or modifying without his express permission.

But saying as no-one's been able to contact him, this makes getting his permission a tad difficult.

as I understand it anyway.. I may be able to get it translated from Japanese, but no promises.
