I have published the source code on http://code.google.com/p/kerjodando/source .
The folder that contains the client part of the modification is in http://kerjodando.googlecode.com/svn/trunk/kerjondando/vicent/ .
The server part of the source code that runs on tomcat is missing as I have not got it from the developer yet but it is based on java webstart macro for passing parameters by Micheal Mandel: http://lopica.sourceforge.net/faq.html#hrefargs .
This is used to produce a jnpl file kerjodando that passes parameters about the tracker to an instance of kerjodando.
The syntax is for example:
where http://www.kerjodando.com/desperate_house_wives/ is where the swarms ipfilter file is stored.
Sorry for garbled explanation but I am working on a easy to use model.
