The password method of invoking sudo depends on the UNIX release and the security
policy in effect.  I've used SUDOUSERS to set who has access to this, used a 
special password.  It is not good security policy to use root's password, unless 
login as root is completely disabled, as it is with the Mac (it takes six steps to
enable root login and Apple advises that this is not necessary.)

However, under no circumstances, should a non-admin user run
any Wine application as a super-user through this method.  It causes problems as
files are created with root's credentials and this causes confusion with some 
new users.  Experts (supposedly) know how to fix this.  Running Wine as root should
bring up a warning message, in Windows format (that is with the warning icon) 
advising users that they are running Wine as root and that applications installed and
files created will not be available to all users (as they would be in some versions
of Windows(TM)).  I think this is the purpose of the original request.  I do support this
as a one-time only warning.  Permission to run Wine applications as sudo should
remain disabled as some users know of this function and use it to get around running
and having root's information.
