No, not really -- I'd like to use a client written on top of Twisted in a Zope 
product. So, I'd need the twisted reactor and libraries running in the Python 
VM that runs Zope. Which should be no problem except I suspect that I 
shouldn't be using the (threaded) ZServer then, because I think that would 
mess with twisted (which is not threadsafe for the most part). 

I thought if I'd switch to the twisted http server implementation that would 
take care of that -- no threaded ZServer, no problem. Except that doesn't seem 
to work as advertised, since the zope.app.twisted package is not present, and 
the one on PyPI seems to be geared towards Zope3, AFAICT.

Is that so? Is there an alternative zope.app.twisted package for Zope2?

thx,
peter.
