Re: [Pyobjc-dev] Re: [Pyobjc-checkins] CVS: pyobjc/Examples/Twisted/PackMan newpimp.py,NONE,1.1 PackMan.py,1.2,1.3 buildapp.py,1.1,1.2 newclient.py,1.2,1.3

[Bob I. <bo...@re...>]

We're aware of that, and have discussed it at length with Jack in the  
MacPython channel.  Basically the deal is that it's using Twisted right  
now, because that's what's easiest, but will be refactored to be  
pluggable later once it works.  When it works, we can distribute a  
--semi-standalone version w/ Twisted, then begin work on a version that  
can live in MacPython 2.4 that would use whichever mechanisms are  
appropriate and available.
