1) you should really get the 4.1.5f build if you are using any of these.

2) I don't know how you are going to speed up the download. Sometimes limiting the upload speed helps but generally you don't have much influence on the download speed.

Why not just do this: Get Limewire Basic and BitTorrent (from www.bitconjurer.org . I prefer this official one mainly because haven't bothered to try any of the others except the Tomato one wich was exactly that IMO) and use BitTorrent to dld all the torrents you want while you wait for the Basic/Pro version of LW that will support torrents? I dunno, but BitTorrent gets me great speeds (much like LW actually) and it doesn't need configuring (or at least mine doesn't). I luv them both.*sigh* I wish they were my kids. Not.
