We are moving from passive to active isolation now. The isolation that we need right now isn't too challenging. The hard part is ensuring that it doesn't disturb other properties of our instruments. We are sensitive to nanoradian rotations at millihertz frequencies, so we have to ensure that our isolation systems don't add any rotation noise.

Regarding isolation-as-a-service: Most of these kinds of experiments run for many years in a university setting. The environmental requirements for each instrument vary widely, too. "Isolated-environment laboratories as a user facility" is an interesting idea to consider. I'm not sure if it would soar in the academic-research marketplace, but there might be a niche somewhere.
