I am looking for a code signing certificate that will be accepted by Java Webstart. It is for the [Arianne Project](http://arianne.sf.net) (a [ten year old](http://sourceforge.net/blog/potm-201003/) open source project hosted on [Sourceforge](http://sf.net/projects/arianne)).

Unfortunately being "just" a spare-time open source project means we cannot proof our identity by posting extracts from the register of companies. Another issue is that code signing certificates seem to be rather expensive. 

So if anyone has suggestions where to look, i will be very thankful.
