Called 'Jython', it's actually a python interpreter in Java, that allows Python code to interact seamlessly with Java. What I'm saying is that there might be an excellent case to use this mechanism to gradually migrate the Freenet codebase over to Python - it can be moved one class at a time, without undue drama. Once Fred's fully in Python, there'll be some huge advantages. For one, Python programs can be readily built into binaries that run on their target system without needing a Python environment. For another, interfacing Python to C is effortless and painless, especially given Pyrex - the Python/C interface language. Python code can compile to vanilla C, and be incrementally optimised for speed. For another, Java is just Pascal with a makeover, and a pretty bad one at that. Python is a way cool language, that lets you get the job done with far less effort and much more fun. So what I'm proposing is an incremental migration away from Java and towards a Python/C blend. Python for the comfortable effortless abstraction, and C for the raw bit-bashing grunt. A big argument in favour of this is that it's not an all-or-nothing deal - stable working code can be released at many different points along the migration path. Thoughts?

Java memory performance is terrible, and saying it'll get better in future is no excuse. It's not just the fixed base either, I've yet to be convinced that freenet by design actually needs 120M of virtual memory. Note that java's memory problems are also adding to it's slowness. But either way, let's face it, we're not going to be able to get rid of java for freenet for the time being anyway, so this discussion isn't going to lead to much anyway.
