I noticed today that el reg said "Spookcall, the UK's first caller ID-spoofing service available to the general public, has decided to close less than one week after launch."
Their spokesman had said previously a couple of days before that they (Spookcall) had sought legal advice and everything was hunky dory (my words).
I wondered if the company they sought advice from was also the same company advising BT in their webwise trials.
