Auto-find sources would create incentive for users to keep their clients running over longer periods of time, hence improving the health of the network. Without an "auto-find sources every n minutes" feature, users would restart LimeWire more often because LimeWire does auto-finds sources only at the start of a download and on restart of LimeWire.

From my usage experience, auto-find sources is something that just work, and LimeWire doesn't have it. Doesn't LimeWire even block other clients on the network that try to do this? Which is more of a true disaster -- LimeWire that does auto-find sources once every week or a LimeWire with users clicking "find more sources" every split second?
