Shareaza introduces yet another innovative feature: Collections!
Peer JS is a Java Script library that simplifies Web RTC peer-to-peer data, video, and audio calls.
You as the developer would have to write different code for every browser that you plan to support. The API that it exposes is easy to use and understand which makes it a really great candidate for implementing cross-browser Web RTC. The reality is that there’s always a server which bridges the connection between peers.
Two or more devices can’t just magically create a connection out of thin air.
Shareaza can connect to up to 4 separate Peer-to-Peer networks, providing access to hundreds of thousands of diverse users, all from one single program.
You can download/upload from these networks: EDonkey2000, Gnutella, Bit Torrent and Gnutella2 (G2).
