This was what I talked about a year or so ago it is also know as Skin Suits, Space Activity or Mechanical Counter Pressure suits.

Dava Newman was at the NIAC meeting here in Seattle in October. She is a pretty good speaker. She talked of a paint on suit.

This would vastly reduce the weight need to be carried around on the surface.

Gary or someone recently was talking up the Hardsuit from AMES.

That kind of suit has some major problems with center of gravity weight and the mobility is achieved thru rotary bearings. The thing that was failing on the Moon at the end of each mission was the rotary bearings. You could reduce problems with Hardsuits with good engineering a the use of lighter materials but my feeling is Soft suits (pressure suits) or MCP will be the primary suit used on the Moon or Mars.
