Well, to continue quoting the 1995 NCAA Hockey rules:
 
4.7.c.  If a goalkeeper, in goalkeeper's equipment, participates in the play
in any manner while beyond the center red line, a minor penalty shall be
imposed on the player.  However, the goalkeeper may proceed without
participating in the play to the players' bench if it is beyond the center
red line.
 
BTW, $3 to NCAA Publishing, P.O Box 7347  Overland Park Kansas 66207-0347
will bring a postage paid copy of the Hockey Rules.  ($3 extra for first
class and $20 minimum order for credit card purchases.)  Throw in a request
