Andrei reported preliminary consideration of the same problem in frequency domain, see Andrei's talk. Three correction methods were considered: inertial stabilization, position feedback and position correction.
Tom Mattison (over phone) described recent progress on vibration level measurements in the UBC, see here an example of the spectrum. This spectrum show similar amplitudes as in DESY-HERA environments. Tom also described how the UBC test setup for the stabilization involving optical anchor would look like.
