You guys shame me. I watched the movie and enjoyed it immensely but didn't catch the NMAP reference. I need to watch the movie again though, was she hacking from within the same intranet or supposedly from a remote location. If she was remote then the IP found would never have been detected since it is one of the reserved addresses and would not have been passed by intervening internet routers.

I only point this out to attempt to retrieve a little dignity from the fact that I missed the whole thing in the first place.

However, I like the speculation made earlier that with Neo affecting the sentinels there might be an underlying second matrix. However it might also be that he has developed an affinity for the signalling used by the machines and computers. They would need to have a way to communicate and monitor their sentinels so it could be this datastream that was picked up either by his interface or, do we dare go here, ESP and he affected things that way. However, I still like your theory of a matrix within a matrix. Just how deep does the rabbit hole go?

Let me just state that I really enjoyed the second movie. It is too early for me to compare or judge it vs. the first Matrix. I can say that like the second Star Wars I was just happy it wasn't a cheap knockoff exploiting the popularity of the original but was a good time in its own right. Whether it is better, equal, or less than the original does nothing to affect that in my opinion a series of good movies is always better than one good one. Godfather III was not as good and I and II (IMO) but it is part of a great series. Indiana Jones, Star Wars, Back to the Future are great examples of where the series is made better by a series of good movies and while one may stand out to one individual over another the whole is strengthened by each. Now we have two more classics being added to this list with the Lord of the Rings and the Matrix series (some may add the Terminator series here too and I would not be opposed to that inclusion). It's a good time to be a Sci Fi and movie Fan.

Finally I also stayed for the preview. All I can say is that the credits are so long it isn't worth it. It isn't a bad preview but you know you will see it a bunch before the third one is released. Like a good trailer it entices but does not give away the direction or plot of the third movie. Stay if you like but I was not impressed enough to recommend it.
