So I think I'm finally beginning to see the underlying reason why Van is 
desiring this consistency:  It is not that he wants to check in his 
installation of Python, but that he wants to check in his installation 
of his packages and scripts into a source control environment, and then 
be able to check out that source control environment into an 
installation of Python on another machine of a different architecture.  
In an environment where a source control system is pervasive and well 
used, this would be an effective deployment alternative to developing a 
packaging/distribution solution using distutils, distutels2, packaging, 
easy_install, eggs, or peanuts, or any other such scheme.

But!

Source control environments don't lend themselves to being used for 
anything except exact replication of file and directory structure, so 
when the different architectures have different directory structures, 
this deployment technique cannot easily work.... except, as Van has 
discussed, by tweaking the development machine's environment to match 
that of the deployment machines... and that only works in the case where 
the deployment happens to only one architecture, and the development 
machine can be tweaked to match... but deploying to multiple machine 
having different architectures and directory structures would be 
impossible using the source control deployment technique, because of the 
different directory structures.

If Van stated this goal in this thread, I missed it, and I think it is 
the missing link in the discussions.  If I'm wrong, apologies for the noise.
