[plt-scheme] Spy

Does anybody know something about the Python in PLT Scheme project?
There is one conference paper [1] and one defunct website [2] which had 
robots.txt blocking so it's unavailable even on archive.org.

I was interested in the source code because Python was my top language 
before I got to learning Scheme and I would love to learn something from 
it (or even use some pieces in my own work). :)
