Having a dynamic IP I've noticed two problems related to IP changes in a same session of LW:

1) On downloads, LW doesn't detect that IP have changed and shows a download speed of 0KB/s for a long time before going into "more sources need" (when there is no download mesh or a little dl mesh)
-LW should detect the IP change, time out those connections and request again download ranges from the previous uploading hosts.

2) On uploads, clients loose the source of the files they were dling
-LW should send a queryhit to those IP so they can continue dling from the new IP without them making a new search in the case the download mesh is inexistent.

Ciao
