Hi,
Our project has been approved for testing in Emulab! Emulab is a testbed for research and development use. They ask that we link them from our project page, so here it is: http://www.emulab.net/ . Emulab is hosted at the University of Utah. We'll be using it to test our jcrowds implementation and to see how it scales.
Cheers!
We are doing this for a class project at the moment and still very much in the early development stages. We'll post a news item when we have some working code. Thanks!
