Soho no-go

" SOHO NO-GO
PEOPLE walking past three rogue strip clubs are getting TEXT MESSAGES warning them to stay out.
Westminster council started the scheme yesterday in a bid to close down Soho's "clips joints". Anyone withing 30 meters gets a text on their mobile via Bluetooth, saying: "Dont enter." [The Sun, 01/09/07]

Thought this was a very interesting yet invasive use of new technology. Will everyones texts be full of ads the same as our emails from now on?
