The course was a revelation: rather than being a critique of any bad habits, the course focuses on existing strengths and provides a number of tools for making best use of them. I know that the next time I stand up in front of an audience I'll be able to talk with a lot more confidence and to far greater effect.

Good presentation skills are an important and valuable asset. Selling the benefits of an information security program or project can be challenging so it's good to be armed with a good set of techniques for getting across the right messages regardless of audience or the amount of time available.

The company will upgrade the firmware for its BT Business Total Broadband customers, which number 170,000. By flipping a switch, the business's modem will create an outpost of BT OpenZone, using a separate SSID, and a "secure Internet channel," as the press release describes it, which means a VLAN or similarly segregated connection that prevents access to the business's internal network.

The notion is that visitors can gain Internet access by using an existing OpenZone subscription, paying a fee (the business can sell vouchers), or being a member of a roaming network. The business customers receive 50 to 500 minutes of use on OpenZone each month themselves, based on their BT contract for broadband.

This business hotspot option extends a previous relationship for residential users with Fon that allows BT home users to flip a switch and become a Fonero.

These kinds of organic extensions of networks have very little impact on the party that's sharing their broadband, because there's almost no work involved. But if enough people opt in, it can have a large impact on the amount of hotspot service that's available. While I have critique Fon for its backside-utility quotient--how readily one can get work done or even make a phone call at many Foneros' locations--the BT business plan assures that hotspots will be in places where people work and gather.
