3. I agree - this whitening will be handy to have for diagnostics.
4. I think in principle, we can ask a company to make the custom cables for us to save us some hand labor. Rich/Chub probably know the right companies to do small numbers of dirty cables.
5. Can't we just a single Noliac PZT in the same way that the OMC does? Or is the lead time too long?
