Hi Qwer,
That's a dangerous precedent. Because even if you trust one another, do you all trust one another's e-mail? What happens if someone clicks on a link to an XML file that installs an XSN that is full trusted and which then decides to stomp all over your hard drive? I wouldn't do that. Sure there is a way and it's documented in chapter 8, but I wouldn't do it... :)
