That works because either you use packages that don't have much hard-core
compiled dependencies, or these are already installed.
Think about installing VTK or ITK this way, even something simpler such
as umfpack. I think that you would loose most of your users. In my lab,
I do lose users on such packages actually.
Beside, what you are describing is possible without package isolation, it
is simply the use of a per-user local site-packages, which now semi
automatic in python2.6 using the '.local' directory. I do agree that, in
a research lab, this is a best practice.
