If they make internet players licensable, then they will have to have some sort of login. Otherwise they'd have to charge everyone (and probably every office) with a computer.
Personally, like rollinstok (#20) I also haven't had a TV for years and don't miss it. For one, I'm never in, being either at work, out socialising, or on one of my bikes. If I'm at home I've got a stack of music to spin. If I want to settle down with birdage and watch something, we bung a DVD in the computer. (No adverts! No wannabe z-listers! No bad news!)
My point to the licensing people went along the lines of:
I have told you repeatedly that I do not have a television. Your recent barrage of threatening letters I find offensive. That is no way to treat a customer, even supposing I were a customer. I know you find it hard to believe that there is a house without a telly. However, being a small minority doesn't make me a liar. I despise and reject over 50% of what you produce. The remaining percentage I am willing to sacrifice for more social or gainful activities. I accept that some people like it but I do not wish to fund its production and dissemination. Why would I waste my time watching cheaply-made formulaic mental chewing gum or UnReality guff like Why-Factor, I'm a Wannabe, Get Me on Telly, Poncing Around on Ice, MasterFoodCantCookCanSwear, Bigbitchysister or some awful depressing soap that removes any residual faith in human nature that I may have had? You are welcome to send your heavies inspectors round again; they will find neither a television nor an aerial. Most likely, they will find that I am not in, just like the last time they came and left their little card. Despite it being my right to refuse entry to them without a warrant, I have generously offered for them to arrange a time to come, such that they may carry out their inspection successfully. However, you have rejected this offer on the basis that you do not trust me. That being the sole basis of our 'relationship', I look forward to an immediate cessation of contact from your organisation. Failing that, you will just have to keep sending your minions on wasted journeys. Which would be a waste of this precious revenue you wish to collect. Your choice. Now please either leave me alone or readjust your notion of customer service: due to the unique way in which the BBC is funded, you are harassing innocent non-customers.
Strangely enough, after this, they accepted that I don't have a telly and watch stuff. Now I just have to reply every 2 years to something that asks me whether I have succumbed to mass culture and peer pressure and bought myself a telly. I wish I'd have thought of rollinstok's "I would pay the £1000 fine if they find anything, they give me £1000 if they don't." That is genius!
