Choose your own P2P peers
Open source peer-to-peer file sharing software LimeWire released an Alpha of LimeWire 5, which features a complete overhaul of its rather unfriendly user interface. If you’re geeky enough to care, you can read more about its background components here. But what’s particularly interesting is that it now integrates the free and open instant messaging service Jabber. This lets users chat, obviously, but it also allows for sharing files with individually chosen friends instead of opening up your share file to everyone else on LimeWire.
