I think the real story here is two fold;

The first is [obvious]:
More pages with Malware contained 'London' because of those Geo-Spam ads that usually come from Virus-laden ad networks. "Hot Singles waiting for you in London!" You know those ones. Facebook does it too, just a little bit less flagrantly.

The second is the fact that Vodafone UK is serving up Malware. That's awesome.

A quick in-page skim and search does not appear to show anyone else having already said this:

It'd be interesting to see if Brad (yes, of LiveJournal fame) does something like this, given (1) what he's already done and (2) what he's mentioned he'd like to do.

He's already rolled his own automatic/wireless garage door opener;

Also in Part 1 you'll see that it was suggested that he put his multitude of in-home access points to use, and use it to let his Android determine where he is in his house, and wire up some other basic utilities to use this data.

If he gives every light switch an IP address, then the room can light up as soon as he goes to enter it.

That would be nothing short of amazing. He would never have to raise his arm to flick the switch ever again!

And when he wants to be social, he can just broadcast his EXACT position. It'll be like Britekite on Steroids! :P
