I managed to achieve 'hello world' in spe, albeit with some annoying benign exceptions coming from something wx isn't finding.

One more note: When spe runs a Python script from within the IDE, it gets the default (64 bit) Python.  I think I've found the place where this could be adjusted.  It looks like spe is no longer being actively developed, so I haven't found the right forum for questions so that I can get confirmation.

spe needs to run 32 bit, since it uses wx.  There is no reason it should force the code under development to run 32 bit, unless the user has a good reason to make that happen.  I'm thinking that for both idle and spe, the sub-shelled variant problem can be handled by wrapping the launch of the ide in a script that exports VERSIONER_PYTHON_PREFER_32_BIT -- the environment variable will get passed down to all subshells, correct?
