In regards to shielding of relativistic starships, especially during high risk transitions like the Urtur system, I found this in _Chanur's Homecoming_: (DAW, p231-2)

"...a hellhole for inbound ships, where dust and rock could break down a starship's defensive bubble and strip away its V. Hit the thick of it at their present velocity and they would make a UV glow, particles accelerated by the contact with virtual particles they brought with them, exotics shooting off in ricochet fashion and creating an accelerated maelstrom of reactions that would bleed away their energy. Ships had to dump when they reached a gravity well; but cloud like Urtur's had ways of doing it for a ship....
...getting through the V shield, chewing away bit by bit in pyrotechnic decay, until it got to vulnerable realspace metal and quasimetals, and got the vital vane-surfaces, and gnawed away at the hull till it began to glow. ..."

(p245): "Urtur dust screamed over the hull, shields downed during the low-V of their turn and reacquisition, dust abrading the vanes."

The references to "realspace" and the ability to turn the shields on and off during manoeuvring imply that the shields may be some type of projection, possibly related to vane technology or hyperspace itself.

It means the shields must:
1) Have mass and be loosely tied to the ship, thus in danger of being lost in a turn.
2) Have some sort of gyroscopic effect, and be incapable of being redirected.
3) Draw so much power that they can't be used at the same time as the drive. (though at Urtur, a sensible hani would just use the drives at very low power and turn *very* slowly.)
or, my favorite,
4) They use the same mechanicals (the jump-vanes) as the jump drive.

Except why distinguish between them and "realspace"?

Possible.

Nothing really to support this.

Mine too. I think this is the most likely from the description.
