Skype alternative but Open Source

-
Skype is very contradicting to Open Source spirit
- It uses proprietary closed and encrypted protocol (closed also means weak);
- Written using obfuscation in software (decryption and checks also uses additional n800 power and resources)

Skype Detailed Analyzes that I enjoyed reading - WhitePaper from BlackHat Europe, March 2006 -
http://www.secdev.org/conf/skype_BHEU06.pdf

- According to latest reports it reads sensitive user information (many /etc files, Firefox Profile, and many others) and nobody knows why (because software is closed source and obfuscated) and how it can be used by crackers.

Detailed discussion at Skype forum could be found here

So, Wengo is viable as alternative to the Skype.

Even more interesting is the following question: How do we use this to our advantage ? It is Simple , we need to disguise ourselfs as the googlebot, many sites will let you in without authentication/registration. The parameter we have to change is called the User Agent. The user agent defines the browser and version that you use. For example it would show Internet Explorer as your browser if you are using this one. You need to alter your Browser settings to t...
