You – can – communicate with the H8000 from any DAW sending MIDI messages. You can assign any parameter to any MIDI controller, then send the MIDI controls to the H8000.
But you understand this is far from "total integration".
Plus, the amount of MIDI data (and more generally control data) that the H8000 can process in a given amount of time is limited. This might be a problem for a plugin to come to light at all. My guess is that it's the reason why E-Control does not exist. Just my 2 cents, of course.
