access restrictions / sandbox

[Ioannis Nousias]

Hello wine developers,

I'm running Wine on Linux. Is there a way to restrict wine from 
accessing some folders and/or resources? Ideally have Wine restraint in 
its WINEPREFIX directory and configure what resources it could access 
(like network for instance).

I've seen few talks on having a 'sandbox' that date back to 2002 and 
most conclusions suggest that access restrictions should be made on the 
host OS. If that's the case, any tips on how one could do that in Linux 
would be appreciated.

Thanks.
