Actually, this falls into the category of 'special spec_procs'.. What I'd 
do is, in the movement code, when it checks to see if an exit is 
legitimate, it will also see if any of the mobs in the room have a 
SPEC_PROC bit set (or whatever the flag is, I forget). If so, It'll jump 
to SPEC(random_blocker).. this will have a structure with the VNUMs of 
all the mobs that are random blockers, with the exits they block. For 
example: (My C may be wrong, but I just woke up, so.. =)

typedef struct {
	int	vnum;
	int	exits; /* this would be bitwise */
} mob_rand_blockers = {
	{1487,	(1 | 2 | 8)},	/* for example */
	{0,	0}

If you know anything about C, you'll recognize that and correct any 
errors I made =) But you get the point. You'll have mob_rand_blockers 
defined in your SPEC, and it'll check to see if the mob in question is a 
random blocker, and you code it to prevent a person going thru the exit.
