Acromantula Venom

I wonder if Acromantula venom will come into play in book 7.  We are 
told that it is difficult to get, and costly.  But what is it used 
for?  Are we ever told?  Would it have any effect on a snake?  Will 
the children of Aragog have any part in the killing of LV? 

I can't remember what we are told in earlier books about Aragog. JKR 
has a way of dropping hints here and there that turn out to be 
important later, but at the time seem like nothing. 

For example in HBP at one point Ron is looking in a broken mirror. 
It is just a passing comment. But we know that is can't be a passing 
comment, because it reminds us of the 2 mirrors that Harry and 
Sirius have/had. And all of that drinking in HBP, I really didn't 
see it, believe it or not, when I was reading it. But there *is* a 
lot of drinking, which I think is a set up for us for the drinking 
that DD does later in the cave. 

Any ideas about spider venom??
