Richard Jones' Log: Perhaps "PyPI" will do
After polling around for ideas, and looking at the various alternatives, nothing really grabs me. "PyPI" captures the nature of the beast we've created well-enough. It's not too silly. It's short. It's in place. I think I've decided that it'll do.
Maybe the potential for confusion was overstated because of the proximity with the PyPy people during the PyCon Sprints. The pronunciation really isn't an issue... It's only potentially confusing when you're in the same room as the PyPy people. Even then, it's pretty clear what you're talking about when some additional context is supplied (eg. "Is your package in PyPI?", "Grab XYZ from PyPI")
And hell, PyPI was named first :)
