And who would care? Skype gives its client away for free... What
can you do that the Skype client cannot do for you? The story is
fishy, and remains fishy.
Dave asks the key question, what good does this really do, even if
true? The blog post says, among other things,
"Indeed the Chinese company's understanding of Skype's technology
seems to be one of their most powerful strategies to protect
themselves in case Skype tries to retaliate. They have developed
Skype blocking technology which they claim is fool-proof and
extremely effective. (See VoIP Predictions for 2006 number 4.) They
hold in their hands the key to enabling telcos to block Skype in
China, all of the Middle East and Africa. Zap! Forty Million users
vanished without a trace!"
The fact is, a telco ability to identify and block Skype packets
already exists.
Narus Inc., of Mountain View, is one company that has developed that
ability and sells it to incumbent carriers. See http://
www.spectrum.ieee.org/oct05/1846 for a complete description. Since
that article was written, the company has also sold its software to
Shanghai Telecom, so at least one Chinese carrier is already using it
right now.
