I challenge anyone to point to a code section that prohibits using one properly sized grounded conductor for multiple circuits as Greg described or for any branch circuit wiring.

The 2002 NECH even shows how it is done. [Linked Image]

Exhibit 225.3 A 120/240-volt, single-phase, 3-wire system (branch circuits rated at 20 amperes; maximum unbalanced current of 80 amperes).

FWIW I do not understand the worry expressed in loosing the neutral, if we worry about that than how would we install feeders or services?
