I would like to thank the conference organizers - it was very good
conference, given it's size.
My talk is available in a text form on codespeak (as are more or less
all pypy talks) http://codespeak.net/svn/pypy/extradoc/talk/rupy2007/
including demos.
Regarding running demos, some are simple, some are more difficult and
needs pypy compiled with specific options, although pypy documentation
explains most of it (http://codespeak.net/pypy/)
Cheers,
fijal
