Why not just keep developing Roxen 1.3?
Roxen 1.3 is a dead project. We could not possibly get the necessary freedom to develop the server the way we want (starting at such a simple level as write CVS access). If we had chosen to do this, it would have been “A Patchy Server” all over again (i.e. we would have had to work with patches to the Roxen 1.3 source). Also we want to continue development in new directions instead of just fixing problems.
