Hey, great idea.

For another employer I did something similar which looked up the 
"missing" package in a local pypi cache/proxy thingy.  Redirecting... Hm :-)

I *think* I'll use this redirect trick in combination with a local 
sdistmaker-made simple index [1].  Then I'll just use my customary 
buildout techniques to get repeatable builds.

For the arcgis-wants-it-in-sitepackages-on-windows problem I'll have to 
fix up something else. I suspect a custom index (with Tres' compoze to 
manage it) fits that bill just fine.  Ok, I'm off setting stuff up.
