The *only* change in semantics I'm proposing is for users of
IronPython 2.6 which is not even at final release yet. CPython users
would be unaffected.
Sorry for top-posting, mobile device.

I really like this scheme. The important thing for IronPython is
that we can get it into Python 2.6 (along with other fixes to make
distutils compatible with IronPython - like not attempting to

I don't think my proposal will land into 2.6. The changes are too
severe
for a bug fix release.
Right, certainly not adding umpteen new sys attributes. :-)
The problem is that the alternative implementations run well behind
Python-trunk, indeed it doesn't really make sense for them to put a
lot of effort into implementing a version that is still in
development. The result is that they discover incompatibilites after
a version has gone into 'bugfix only' mode.
Whilst the fix you have described (add information to sys that is
used by site.py and distutils) is ideal it can only go into 2.7. I
would *still* like to see a fix in 2.6 - even if it is simple logic
in site.py using sys.platform (if sys.platform == 'cli'; elif
sys.platform == 'java' etc). That way IronPython 2.6 is able to be
compatible with Python 2.6. This logic might need duplicating in
distutils (I haven't looked at how distutils works out where the
user site-packages folder is), but it is a 'maintenance only' fix.
But it's still a change in semantics. Tossing this into 2.6 would
mean that anyone who has worked around the current behaviour is
going to have a busted install.
