I know we are free individually to make these changes. However, I'd
like some clarification to verify the command-line thing-ami-bob would
not incur their ire (I'm unclear where they draw the line, and they
have felt very burned at least a few times).

How about something like:
def render(filename="default.pov"):
if os.name == 'linux2':
cmd = ("povray +V +W640 +H480 +FN16 +AM2 "
"+Q9 +A0.3 +P +L/home/urnerk/include +I"
+ filename)
elif os.name == 'nt':
cmd = ('"c:\\program files\\POV-Ray for '
'Windows v3.5\\bin\\pvengine" -V fpp.ini')
# or use r'HKLM\SOFTWARE\Classes\Applications'
# r'\pvengine.exe\shell\RenderAndExit\command'
else:
raise NotImplementedError, 'Not ready for os %r' % os.name
print "Rendering... (this will take some time)"
os.system(cmd)
