DE Loyality Vow

I was listening to a news report about RL terrorist and how they 
take a vow to their leader.  Being obsessed with HP, I, of course, 
thought about the DE and LV.

Why have we not head of a DE vow? We now know about the unbreakable 
vow.  It would certainly make sense that LV would have his DE take a 
vow of some sort. I think that JKR like to be inventive so she would 
not use the same type of vow twice. 

I also wondered about Draco.  It certainly seems that he has a dark 
mark on his arm and he is underage. I wonder if there is a vow that 
DE's take to the Dark Lord and it involves a provision that if you 
betray the Dark Lord your first born will die. If I were a Dark Lord 
that is what I would do to make sure that my followers are loyal!  
And if there were such a provision there might be a fine print 
clause that says "in the event your actions cause your arrest" your 
first born will take your place in the Dark Lord's service. Maybe 
that is why Draco must take his father's place. 

What do people think??
