How are your PHP skills?
You know that you could write a PHP script that says. "enter your hostname..." and it then outputs the new htaccess file contents to screen leaving the user to cut and paste it, save it and upload it.
You could also have the script make the file directly, but there's a lot of security implications you'd also have to take into consideration.
