Often, you talk to someone on chat, and discover that someone has a file the other wants. It is annoying and far from 100% effective to simply search for the file and try to download from them. It would be nice if there were a way to either set up a connection through chat, or more easily give a preference of some sort to a given IP. 'Let w.x.y.z connect even if I'm full, and give them as much bandwidth as they want'. This would enable more direct sharing, and a stronger incentive to share.
