I did this last month, didn't get any publicity.
A client's computer, one that I had previously configured with LogMeIn, was stolen last month.
The stupid thief didn't reformat anything, and within a matter of days the machine was showing up on my LogMeIn dashboard. I don't need to know the IP address for this to happen [even though LogMeIn tells me what it is] because LMI connects to the main server whenever it has an internet connection
[@anonymous coward: it doesn't even need to be logged into XP for this, no password at the machine is needed]
But at this point it got even more interesting, because the detective investigating the theft asked me to install Computrace/Lojack for Laptops on it - through my remote connection -- because that gives them more prosecutable information than just the IP addy [screen grabs, chat logs, pics from the camera, etc.]
Then I had to watch the connection for several days before I got a chance because the thief kept turning the machine off when he wasn't using it. A week or so later, they raided the place and recovered not only the computer but other items stolen from my client at the same time.
All you techies should know this: there's a large number of new machines from Dell, HP, Toshiba etc, that have the Lojack app on the motherboard. All you need is the service tag number and they can switch it on. And since it's on the BIOS, reformatting the HD, or even putting in another one, doesn't help.

I am not hawking Lojack here, because it seems to me this app is a HUGE security problem as it allows virtually invisible monitoring of a machine, you just need someone at Lojack to turn it on. It is a wide open backdoor and now its on many motherboards. I sure don't want it on my machine.
But the client was happy.
