I discovered a way to download this data.
I'm not going to reveal how I downloaded the data.
The reason for this is that the people who own the data, while saying that the data can be obtained and used for non-commercial purposes, have put restrictions on its use (see the statement on my blog post).
However, they didn't actually put restrictions on the distribution of the data, though it remains within their copyright, so I feel it fine to seed these as torrents.
I'm not distributing these in any other format, it is up to the open-source community to perpetuate this and torrent, while often associated with clandestine software piracy, is the way to do this.
If you find no seeds available, then I can re-enable mine.
