Mauna Kea has stringent rules for new developments and `Ohana is highly aware of those. This is the reason why we would propose to use existing floor space for the recombining laboratory, and delay lines. Such a space would need to be relatively vibrationnally free and sufficiently large to house whatever type of delay line finally gets implemented. Possible locations might include, but are not restricted to, either of the CFHT's Coudé rooms (on the telescope pier for reduced vibrations) or the KeckI basement (for access to the existing delay lines).
