This would be cool, especially since Steinberg is pushing ambisonic capabilities - there are ambisonic microphones on the market that could be used to capture peoples own Impulse Responses.
perhaps, if there is already a relationship with Voxengo, they could do some work/implement their Deconvolver code into this plugin.
I don’t have it, but apparently Altiverb has a really easy impulse response convolution maker utility.
