Sorry - but this is a non-starter - you are expecting existing deployed clients to magically change their behaviour to cope with format=flowed inline signed messages. The only way to ensure format=flowed inline signed messages work with existing clients is to use the procedure I outlined (or just not use format=flowed). Yes it is vulnerable to a man-in-the-middle attack but that is true for anything that does not also sign the message headers. A man-in-the-middle that changes text/plain to text/html will result in pretty much the same display 'corruption' without the need to even change the body content, so its not a problem specific to format=flowed.
