How to access Bitcoins from a Bitcoin address

I understand how Brainwallet works - you pick a long/unique pass phrase, it hashes your pass phrase using SHA256, then it's ran through an algorithm to create an address. In order to access the funds within that address you need to know the pass phrase.
Here's what I don't understand: how do I access the Bitcoins within that specific Bitcoin address?
I recently read this guy's contest to hack the Bitcoins from his five different addresses. Once I come up with a guess for his pass phrase how do I test it? Do I need some kind of software? Or can I hit a URL with the address and pass phrase and get notified whether I am granted access?
Yes, I am aware that there are no longer any Bitcoins within these addresses. I'm just curious how the process works.

Brainwallet Hunting Game

Hey fellow Bitcoiners! I have created a new game (inspired by this contest) that involves searching for Brainwallet passphrases in order to gain access to the BTC contained inside! The difference between the game and the contest that inspired it is that hints are given right at the start to make it easier to find the address. It's just in it's early stages, so please forgive the kinda noobish website. Please let me know what you think and what I can improve on! The site is CoinHunt.tk. Thanks in advance!

If a Python script scans 1500 passphrases/sec, how much faster is a CUDA program?

In my brainwallet hacking contest, with simple Python script one core can try 1500 passphrases/sec: http://linja-aho.blogspot.fi/2013/03/bitcoin-brain-wallet-cracking-contest.html
As I'm not a guru in HPC, I'm asking: how many times faster is a CUDA program for that application? My guess is about 100000 times (1000 times for replacing Python with C and 100 times for CPU -> multicore GPU).
