Fwd: Anyone make any sense out of this skype hack announcement?

[Christian Collberg]

The skype client was reverse engineered several years ago:

@inproceedings{biondi06silver,
  title = {Silver Needle in the Skype},
  author = {Philippe Biondi and Fabrice Desclaux},
  note = 
\url{www.blackhat.com/presentations/bh-europe-06/bh-eu-06-biondi/bh-eu-06-biondi-up.pdf},
  booktitle = {Black Hat Europe},
  month = Feb-Mar,
  year = 2006
}

I don't know if the new crack reveals anything new. We have
a writeup about the Skype protection techniques in
Surreptitious Software, our book on security-through-obscurity.
(Sorry for the blatant self-promotion).

    * Understanding the theoretical limits of code obfuscation
    * Detecting software tampering in distributed system
    * Mastering techniques that both attackers and defenders use to
  analyze programs
    * Using code obfuscation to make software harder to analyze and
  understand
    * Fingerprinting software to identify its author and to trace
  software pirates
    * Tamperproofing software using guards that detect and respond to
  illegal modifications of code and data
    * Strengthening content protection through dynamic watermarking
  and dynamic obfuscation
    * Detecting code theft via software similarity analysis and
  birthmarking algorithms
    * Using hardware techniques to defend software and media against
