There was one service like that but it was discontinues on 2001-Nov-17. Look here: http://www.boerde.de/sat/ There are a couple of such services I've found now, let me describe two of them: Cidera Usenet News Service http://www.skycache.com/services/usenet_news/index.php It seems to be avialable only in America, but some sources say that Cidera transmitts also from a satellite over Europe. I have not yet found out what is true. SkyWay news http://www.internet-skyway.com/index_swnews.html This one is only avialable in Europe, it is transmitted on Eutelsat W2 16 degrees East. But this service is bad, because they supply you a proprietary satellite receiver, which has a RJ45 ethernet output. They require you to connect it to two-directional landline internet connection, so they can connect with SSH to this receiver. The feed is probably encrypted with a changing password, and this two-way connection is needed to supply the new password every while. Otherwise everyone could receive the news, which would be very good for the world, and it would not cost the company a penny more (it would even cost them less as they would not need to connect with all the receivers with this SSH). Here is a thread about DirecPC news cast: http://groups.google.com/groups?hl=en&ie=UTF-8&oe=UTF-8&inlang=en&newwindow=1&th=52e0b9e1c9923d4c I've heard that DirectPC had plans to swith to a DVB compatible system (they used a propiretary protocol, which required to use only DirecPC cards). Does anyone know if that is true. There is a site here saying that DirecPC is now avialable in Europe: http://www.direcpceu.com/ They transmitt off HOTBird 3 stellite at 13ยบ East. Their serice does not require a constant landline connection, so it seems everyone can receive the news for free. There may be many more such services, and maybe when we search more, we can find a newsfeed which can be received by everyone without any subscription, just by pointing the antenna to the right satellite, tuning to the right frequency/symbol rate/polarity, and listening for the right packets. I would look more close at this pressrelease: http://groups.google.com/groups?hl=en&ie=UTF-8&oe=UTF-8&inlang=en&newwindow=1&th=5fe99c5122cb9dc0 I nave mo time now, I have to work, would be nice if someone could investige this subject more deeply. > Problem would be, as always, encryption, since shared-secrets will never > really work. I do not understand what you have in mind here. We want it to be receivable by anyone free, so there is no point in encrypting anything. There is no point in encrypting Usenet sat-ffed too - it's all public anyway. On the WWW you do not encrypt any sites exceptyour logon to your bank and a couple things like that - all else is meant to be accessible by anyone. -- Miernik ____________________________________________________ ___ ICQ: 4004001 ___/___ tel.: +48608233394 ___/ mailto:miernik@ctnet.pl No Iraq war! http://www.globalexchange.org/campaigns/iraq/invadeIraq082702.html Please call the White House +1-202-456-1111 or fax +1-202-456-2461 and say no!
