[Wine] Re: [Wine 1.3] Access to "/" for Windows Applications

[DanKegel]

First off, "winetricks sandbox" almost does what you want,
except that "wineboot" (or installing ie6, or anything else that reboots
windows) will undo the sandboxing (there might be a wine bug there),
and that malicious code can very easily escape (e.g. by running native
linux code).

If you want a somewhat more secure sandbox, you could try to run wine
in a chroot jail.  This is annoying but might be worth the trouble for a few
users.  If you really want this right now, see
http://media.codeweavers.com/pub/crossover/case_studies/WineAndSecurity.pdf
which says CrossOver already supports this.
