Very cool work.. and frustating running into walls imposed by manufacturers, I imagine! I've also been working on GPU-based audio plugins for a long time and have done some public material on the subject.
Just my two cents: have you considered using a server/daemon process that runs separately and therefore more controllably outside a DAW (and therefore a client-server approach for your plugin instances)? It could allow you to have a little bit more OS-based control.
