Since it's about Twisted/SSL/PyPy, I'll at least reply to this one. :) 
If you want to discuss any the specific technical issues in more detail, 
there's a separate pyOpenSSL mailing list hosted on Launchpad:

That wiki page was updated when pyOpenSSL actually did mostly work on 
PyPy.  However, unfortunately, PyPy has changed in ways that mean it no 
longer works at all.

I filed https://bugs.pypy.org/issue1069 a few days ago about the current 
problem.  The missing APIs are the CPython thread-local storage C APIs. 
They're just a thin layer on top of the appropriate platform-specific 

I presume that memoryviews _also_ still do not work.
