I wonder how soon Airnav would change the software options, if they were used as part of the defense by a user, when charged with disclosing restricted information, from an unlawfull intercept!!!
Bear in mind that even Microsoft now give consideration to European laws after the EU fines.
Airnav the comment that it may be unlawfull to share in some area, and then forcing the option to share ON is NOT a defense in UK and European law.
A patch to support the change, possibly via a registry patch - would be an option.
