If anyone's wondering how I did it, I went onto the spider maps page, and for each of the 33 London Boroughs I copied and pasted the links into Excel, and by use of a magic Excel Macro I nicked off that there internet, I made a text file full of weblinks to all of the individual files, and got some clever little freeware program to download everything in that list. Except it missed out a few, so I painstakingly went through them working out which ones it hadn't done and manually downloaded them.
My point is, that I'm a really nice person for doing this, and if at some point in the future anyone who's downloaded the zip file feels like buying me a pint, it'd be much appreciated

It's an 85MB zip file, which shouldn't take *too* long to download using a broadband connection (around 12 minutes with a 1MB connection, faster with a faster connection). But it'll take me until around 11:15am or so until it's finished uploading (which is much slower than downloading), so I'll post the link then, when I've tested that it works ok.
