Adding a user mount should be scriptable. The actual home directory is the next to last entry in the user's `getent passwd' output. In a profile script, this entry can be used to generate a user bind mount from the actual dir to /home/$USER. Then, set $HOME to /home/$USER.

Slightly edited: Ok, I see. So where exactly is the problem? Variable which already exist in the env are not overwritten ($PATH). Variables which only have a meaning for Windows apps should stay in DOS notation anyway. So what's left? TMP/TEMP/TMPDIR? If that's all, we have two choices, either convert them, or skip them. What's better?
