Yes, I agree with this.  What I meant is that when I first read the original
paragraph (the 1st one quoted above), I thought it meant that in the future
py2exe and Psyco could be combined in such a way that we'd essentially have a
compiler from Python producing a "classical" compiled binary.  A lot of people
could read it that way.

The question is if we should advertise a Psyco+py2exe combination using a
similar wording, such that it superficially sounds like we are doing a
"classical" compilation from .py to .exe, whereas it actually means that we
are hiding Psyco with the bytecodes in a .exe.  After all, from a user's (or
journalist's) point of view the result is similar, performancewise.

Whether Psyco is reliable enough for this is yet another issue...  I'd
classify Psyco as "mostly reliable" only...

A bientot,
