As I wrote in my previous mail: TeX Live Manager is the main reason
for a single-user install as default. We could add a warning about
it, but more text means less simplicity, and people don't read those
texts anyway. No solution is going to be optimal for everybody.

The client scripts at http://www.tug.org/texlive/w32client.html are
written for a different situation, but they do create path settings
and file associations for an already present TeX Live, and could
make TL usable for the second sister.
