I didn't say anything about a sat system. If I had the money for a
NuytSuit, wouldn't need a sub as a surface support vessel would be less
expensive to operate and could get more places faster.

A complete system for sat diving is a pretty large system. And again
if you thinking commercial then a submarine can no longer compete
against a surface vessel. The number of crew during sat diving is
large. And all of the requirements for backup and rescue is
tremendous.
