The Kreacher-Mundungus-Regulus Connection

This may be old hat, but since I'm rereading OOP, here goes.

First, I must say I that, after reading BHP, I have a new 
appreciation for COS and OOP.  

Second, I just read the chapters concerning the Black household.  I 
know there are theories floating around that RAB is the person who 
left the locket in the cave in HBP.  I agree, but the point of this 
is not to rehash that -- that theory is simply my point of departure.

I believe others have suggested that Kreacher helped RAB to get into 
the cave.  Well, if Kreacher is required to do what members of the 
Black family ask him to do, then I think it's likely that RAB has 
been Horcrux-hunting since that time and that Kreacher helped him.  
(I'm assuming that Kreacher returned to the Black household before 
Sirius's return from Azkaban, of course.)

There is this great mystery in OOP about what Kreacher has been doing 
for the past ten years.  I think the answer is, he was Horcrux 
hunting with RAB, who forbade him at least from spilling the beans to 
any of Voldemort's followers.  I think he would have to tell Harry if 
Harry asked him, "What have you been up to the past 11 or 12 years?" 
(whatever the appropriate time frame would be when Harry asks the 
question).

I also think it's likely that Mundungus has nicked one of the 
Horcruxes.  Perhaps RAB stored one at the Black household but never 
got the chance to destroy it.  Otherwise, it seems to me the entire 
house-cleaning-Mundungus-RAB plotlines add little to the story.
