Ah, I sort of assumed (since you mentioned Twisted) that it was a
server you could start up from scratch completely under Wing's control
and then take it to the point of failure just letting Wing's normal
exception catching mechanism work - thus, just starting it from the IDE.

The exception trapping support of Wing, BTW, as you also mentioned, is
definitely impressive since it's the only one I've seen that can cross
the Python->C Extension-Python boundary and still trap an exception.
Works great with exceptions in wxPython applications since those all
occur on the other "side" of the wxPython extension, and aren't
generally caught by other debuggers i've tried.  Of course, this does
occasionally catch "normal" exceptions suppressed by such extensions
that you then need to ignore, but Wing makes that simple too.

The environments I was originally envisioning were those where you
really couldn't manually start the application directly from Wing.  So
in the web case, something like Apache using mod_python, or perhaps
when trying to debug a COM server that is initiated as an in-proc
server from a C++ application.

But of course that mechanism is just as useful even if you could start
your own application, since it lets you minimize the debugging
overhead until you actually reach the right point (which might be
after some unknown amount of runtime).
