I've implemented most of these requests (not USB ) -- new alpha is up at http://www.batmanthehorse.com/jemplode/jemplode20.jar ... network discovery on Windows ia MUCH faster on my machine (apparently, printing out an InetAddress causes DNS to kick in -- so my debug output was reallllly slowing things down printing out a bunch of lookups of broadcast addresses).

A lot of the new little tweaks are in the Options menu item under "Tools".
