Welcome to Rebreather World, Matt.
It doesn't happen often that my jaw drops wide open, but you did it.

I'm sure we can provide plenty of info on rebreathers, but it seems you're
the one we can learn from. It's hard to hold on to a dream and pursue it
against all odds. I understand the dream, but not your will power that'll
make it come true. I am in awe.
I wish you the very best, that you will live that dream.
