This was posted on the Perseus Project discussion list and I suspect will be of interest to a large part of rc's readership:

All of the source code for the Perseus Java Hopper and much of the content in Perseus is now available under an open source license. You can download the code, compile it, and run it on your own system. This requires more labor and a certain level of expertise for which we can only provide minimal support. However, since it will be running on your own machine, it can be much faster than our website, especially during peak usage times. You also have the option to install only certain collections or texts on your version, making it as specialized as you wish. Also, if you want to use a different system to make the content available, you can do so within the terms of the Creative Commons license. This is the first step in open sourcing the code as you can modify the code as much as you want, but at this time, we cannot integrate your changes back into our system. That is our ultimate goal, so keep a look out for that!
