I read the article.

Jonathan Clark, a former NASA flight surgeon and special forces parachutist has a unique understanding of the extremes of spaceflight survival—his wife, astronaut Laurel Clark, perished in the space shuttle Columbia is one contributor to the design team.

..."team of respected specialists. They will help Orbital Outfitters design space suits for their own dives and for other companies’ future space-tourist operations. Tumlinson has hired noted aquatic-dive and life-support specialist Bill Stone [see “Robot Subs in Space,” February] to create the internal thermal-regulation and breathing systems for the suits, as well as their data-acquisition systems. The actual engineering of the suits—that little save-your-life part—will be managed by Tomas Svitek, a NASA consultant and freelance program manager who Tumlinson has brought on to make Gilman’s designs technologically sound."

Turns out it's far less speculative than most of the topics discussed here. Real engineers are spending some design time on the concept.
