I've been aware of Dirac for some time. Its not feasible to use his
license in combination with Ardour without creating a fairly complex
plugin APi. Why? His license is a license for the developer, and it
won't permit source redistribution. Since Ardour links against at
least 1 GPL library, it would violate the GPL to distribute Ardour
with Dirac support as a compile+link time option. I'm not against the
idea of a plugin API for time FX backends, I've just got better things
to do at this point in time, and for the foreseeable future.
