Hi Nathaniel, I would like to suggest one more topic for the workshop. I see a big need for a library (jffi) similar to cffi but that provides a bridge to Java instead of C code. The ability to seamlessly work with native Java data/code would offer a huge improvement when python code needs to work

I meant to mention them in my email as both of them are great options when you don't mind sacrificing some compression for significant improvements in compression and decompression speeds. These libraries are I/O bound when saving to a hard drive unless you are using a very low powered processor.

Hi Kevin, More up to date information can be found on the FAQ page http://doc.pypy.org/en/latest/faq.html#do-cpython-extension-modules-work-with-pypy The best approach for PyPy is either use a pure Python module if possible or use a cffi wrapped extension instead of an extension that uses the CP

Fijal, In the past you have complained about it being hard to make money in open source. One way to make it easier for you is grow the popularity of PyPy. So I would think you would at least have some interest in thinking of ways to accomplish that. I'm not trying to dictate what PyPy should do
