[Twisted-Python] Assistance with using Twisted with "pyinstaller"

Thanks, I'll keep cx/bb-Freeze in mind if pyinstaller doesn't work out. I
did get some tips from one of our internal guys;  they had built a project
successfully with Twisted & pyinstaller some time back. I'm trying to figure
out the details of what went on there. Seems that they made an <appname>.py
which imported Twisted's UnixApplicationRunner() which then imported what
had been the .tac file (renamed to <appname>tac.py) to launch the server.
Still working out the details, imports, etc., but appears that <appname>.py
took over much of the functionality that twistd was providing and made it
into more of a straightforward python app. We'll see how this goes.
