Sure, P2P file sharing may sound
social, but how much do you actually interact beyond a cursory 'please' and 'thank you'? A lot less than you might if LimeWire's vision pans out. LimeWire 5.0 beta
will let you make your photos and such available to just pals on your contact list, or to any other LimeWire user. Right now it works for Jabber-compatible services like Gmail, but if it takes off, other chat clients could follow--good news if your multinetwork app doesn't do file transfers yet.
