x-kad is still in an early stage of development, so your help is more then appreciated.
At present, x-kad is still in a pre-alpha stage. There is no binary distribution, there is just CVS.
So, if you are a developer and feel like sharing some of your time working for this project, contact us.
But even if you are not a developer... there will soon be work for you, mostly on documentation, and testing!
The P2P network, in the form of the x-kad protocol, is almost complete.
The TUN driver is ready to be integrated even though some polishing is still needed.
Basic cryptography has been implemented, even though, depending on the scenarios of application, much stronger and secure algorithms might be required.
