AFAIR, Python is written in portable C ;-)

Any example of relevant platform which is not supported ?
This list already seems pretty long and contains quite some "exotic" arch:

Reread the above points... A Mercurial checkout including full history
is smaller than a simple svn checkout !

with a full local copy of the repo. I often do some developments on
my laptop without network connection, and SVN is mostly useless in
such a situation.
