Microsensor tech is moving very rapidly in this direction.

A central advantage of a nanotech spacecraft would be the ability to self-repair
in fight (see "The Starseed/Launcher", http://www.speakeasy.org/~forrestb).
This might also include repairing biologicals.

Im my proposal, a single shield is replaced with a "convoy" of shields
("point probes") and forward-looking sensors, rather than being 'dumb matter'.
Much less mass required, and the shields can serve other functions as well.
With sensors far enough ahead, it may be feasible to explosively disassemble
the starship to navigate around the larger obstacles, or simply create corridors
through the ship for smaller objects to pass through.
But you're

Could use "leapfrog" braking, or force beams to stand off the shields.
Alternatively, equip each separated portion with its own brakes.

see above.
