If you think Kore is interesting, then also check out Tntnet <http://www.tntnet.org>. I've checked it out a few years ago and it felt good - stable, complete, easy to use etc.
What about performance? One of the reasons to use namedtuple is performance, esp. memory-wise (afaiu nametuple stores field names in class definition, which can save a lot of space compared to lists of dicts). I would expect recordtype to be better than dict but not as good as namedtuple. It would be nice if author posted some benchmarks…
but anonymous is not simply one group, it's an idea... it's very likely there's another independent group of people that orchestrated attacks against sony. they too have the right to call themselves as anonymous, as long as they are.
it's likely anonymous and sony where right first denying and then implicating anonymous' involvement in hacks.
