Yet more perspective-- perhaps previously posted (P alliteration):

Best perspective I have read thus far. Just a few days old. I wonder if more actual orders have been placed and/or some of these companies are ramping on their own dime and/or on spec.
And by the way, back of the napkin activity is something I highly value. But I try to start with the best specs I can. Like considering a vent as part of a setting with a variety of machines, disposables and professionals.
I always try to work with like minded disrupters whom have, at least some relevant experience.
For those serious about these vent efforts and related efforts to help with equipment and devices, these folks and others like them will perhaps be good contacts and/or pitch in:

I met the guy that runs the place last October and I know the couple that provided the funds. Michael Gaulke is a Porschephile and I have raced against him.
Remember, we are all in this together.
