People studied Skype: http://www.recon.cx/en/f/vskype-part1.pdf http://www.recon.cx/en/f/vskype-part2.pdf and found that it contains tons and tons of cryptography, obfuscation and countermeasures against debugging or reverse engineering. A closed source code like that and with an explicit purpose to build a crypted P2P network bypassing firewalls with every trick possible is something to be nervous about. The code constantly checks itself (this is why it uses a lot of CPU) and it decides things it should not (it was said that Intel convinced Skype to cripple multiconference on AMD CPUs to improve the reputation of Intel CPUs). I'd like a good alternative to Skype, even _without_ Skype compatibility. -- Roberto Ragusa mail at robertoragusa.it -- fedora-list mailing list [email protected] To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
