798674 2009-08-06 07:36:00 Its a proprietary system (goes against morales), its peer-to-peer which means your calls aren't going through the most direct route, meaning they can be intercepted, not to mention they give you a false sense that everything is secure...

But according to an article on The Register -

Skype's proprietary scrambling technology is purportedly the bane of electronic spies at the NSA and GCHQ...

That sounds good to me!

798675 2009-08-06 08:57:00 My parents calls overseas and they pick up those calling cards, about the same price as the 4c Skype charges but so much easier that you are using a std phone and so are the other party.

If I was travelling and not staying in a country for long I can see the usefulness of Skype and pay the 4c a min or leave home a Skype handset (that works via the internet) and call that for free.

798677 2009-08-06 11:21:00 Or just use email.

Email to a landline with no computer at the other end.
How do you do that?

798678 2009-08-06 19:44:00 One of may parents friends in the UK has some sort of phone that handles email, it's not a computer. I have never seen it so no nothing about it apart from they have one gary67 (56)
798679 2009-08-06 21:23:00 - Skype includes the ability to send and receive files similar to other peer-to-peer (P2P) programs and services.

- Because the file transfers are over a proprietary encrypted channel (similar to HTTPS) the inbound file transfers can effectively bypass security mechanisms in the same way P2P networks do.

Yet another aspect of Skype is its ability to tunnel though firewalls without the user ever having to write a single line of code.

The tunnel is created without the need for an active Skype call.

Skype Supernode

Skype's official End-User Licence Agreement (EULA) no longer mentions supernodes, but now says merely:

"4.1 Permission to utilise your computer. In order to receive the benefits provided by the Skype Software, you hereby grant permission for the Skype Software to utilise the processor and bandwidth of your computer for the limited purpose of facilitating the communication between Skype Software users. "


When a computer goes into supernode mode, Skype opens up a great number of network connections over TCP (Transmission Control Protocol, part of the Internet Protocol suite).

So even though the bandwidth needed is quite small, the effect is that internet access grinds to a halt with DNS and web timeouts.

798680 2009-08-06 21:55:00 We use Skype to talk to family in the UK. It is brilliant and call quality is excellent. I found it easy to set up and use. We have a stand alone base-set in the kitchen alongside our normal phone. Our conversations are not security sensitive to the great nations of this world so if anyone is listening to us, good luck to them on a time-wasting excercise. :) Richard (739)
798681 2009-08-06 22:12:00 So Chill, is Skype really as bad as you first stated, or have you backed down on your original claim? :( Zippity (58)
798682 2009-08-07 04:11:00 Ah but its not just about the "security" side of it, but the fact you can become a supernode, the way it handles its traffic, the "morale" side of having an open communication system etc etc

Yes, I still stand by my claim of it being evil, not to mention its future is "uncertain" (Though thats still debatable):

Switching Skype to a SIP-based system would be an amazingly awesome way to go, and I would most probably renounce all my previous statements. Until then, I despise it!
