I have wanted that for a long time myself. Not sure why we still don't do it other than there is some trick to properly creating the manefest file for inclusion into the jar (perhaps unix/dos mode file settings (cr/lf)). I have built jars that do work as you mention although generally with collections.jar content included into the LimeWire.jar. collections.jar will hopefully go away soon since it is a version of Java 1.2 collections for use with Java 1.1 (needed for Macs).

The dll is there because we don't build separate jars and some LimeWireOther.zip users are Windows users.
