"rotating seals"
That's the killer problem. I suspect that is going to be a much bigger engineering challenge than most might think. Movable joints in a spacesuit that gets used short term and doesn't rotate all that much or all that frequently is one thing. A rotating, air-tight joint moving constantly is a whole other mess of problems.
