Did a search and didn't see a mention of this, thought some may be interested. I have a Canadian friend with this in his STi. With it he can track his car over the internet, start it over the net, unlock it etc. He can also limit the speed when someone else drives the car and, of course, it is tied to the alam Lojack style for security.
Canada only for now I think.
