... and somewhere around here we end up with what I described as an over-engineered solution. By trying to satisfy everyone's requirements, you ultimately satisfy no-one's. Sigh. I keep meaning to avoid getting sucked back into this tar-pit, and I keep failing :-( Just put me down as a hearty +1 for Doug's "just deploy a script called whatever.py" approach for standalone stuff, and using python -m for scripts distributed as part of larger distributions.
