Really? I don't think so. I imagine it would be much more dependent on 
the amount of computing power the attacker has access to. More encrypted 
blobs won't help. If that was the case then the various encryption 
schemes in wide use today would be cracked already. Bad guys can setup 
networks and blast data through it and have complete access. I don't see 
them cracking encryption.
