Internet & Networking "One researcher has decided he wants to make Skype open source by reverse engineering the protocol the service uses. In fact, he claims to have already achieved that reverse engineering feat on a new skype-open-source blog. The source code has been posted for versions 1.x/3.x/4.x of Skype as well as details of the rc4 layer arithmetic encoding the service uses."

Look at the service - not just the software. Skype is video chat. Skype can connect to PSTN phones. Skype is not a part of something else. It is SKYPE.

Alright, so far so good.

Reverse engineering Skype will achieve nothing positive because the protocol is one part of the whole entity that is Skype. In a nutshell, it's been a complete waste of time from which nothing positive will come.

Wrong. Again, let's talk about WLM clones. You want to communicate with WLM users (a service), but you use an operating system that's either not properly supported by Microsoft or not supported at all (in short, anything but Windows and J2ME). In that case, having a WLM clone allows users of other platforms to communicate using the WLM service with other persons using the WLM service.

Same with Skype.

People use Skype because it provides the service they want and nothing else does.

Skype is a service - not a bloody protocol.

Do you understand the difference now?

I already know. The thing is, it is possible to write alternate clients for using the same service. But that requires knowing the protocol. Hence reverse-engineering the protocol is useful.

What is your problem with that ?
