If you've ever had the misfortune to dial into a virtual private network (VPN) for a spot of long-distance telecommuting, you'll doubtless be overjoyed to hear of a new technique that gives the slowcoach technology a boot up the backside.

As the new method is completely compatible with the SSL encryption used by any internet browser, there are few barriers to commercial adoption - something NTT reckons will happen within two years.
