1) I'm not saying that you compiling such list. I'm just saying that this is 
possible as long as server provides a way to find out if a particular user 
exists.
2) Some people have no any vCard at all. I have several such people in my 
roster. So you will delete valid entries from time to time.

Just give up. Treat this as e-mail address - usually you can not know if email 
is valid or not until you will got a reply from remote user.
