Around here if we cannot find platform.python_implemention()
we just look for sys.platform.startswith('java')
Are there any cases where you need platform.java_ver() ?
I don't know about IronPython

PyPy has platform.python_implementation these days as well. If you
cannot find it, look for '__pypy__' in sys.builtin_module_names
For detecting Stackless my PYTHONSTARTUP just tries to import stackless.
Detecting Cygwin may be important for you. It's a real mess.
platform.system usually gives you stuff like: CYGWIN_NT-5.1
but, alas, sometimes it just gives you 'Windows'.
os.name sometimes gives you 'nt' -- but sometimes it gives you 'posix'.
I've played whack-a-mole with this one for a while, and still don't
like any of our solutions. And the customer threw out his windows
systems and replaced them with Macs, so the problem now is moot for me.
