Thanks to all for your replies. They have been really useful.

Well, the last application I implemented is a Vuze plugin for detection of fake content in the BitTorrent environment which was made official (http://plugins.vuze.com/plugin_details.php?plugin=TorrentGuard). I am afraid my job in that project is over so I cannot provide you with the git repository. However, I have attached a pdf that acknowledges my participation in that project.

I have already joined Trailblazer SIG and Infinispan. I am really looking forward to contributing and getting involved as much as possible.

BR,

David.
