First, you need to understand your target user, is the site meant to be visited by people during working hours or to inform people at companies? My guess is that not many companies have the policy that you speak of, so are you trying to court the companies that do have those policies?

Second, does the site need to be 100% flash? I personally try to avoid using flash as much as possible. It's a good chance that it just happens to be the position that I'm in though, not a formal rule that I have.

Most of the websites that I put together are for people with slow connections that don't need fancy, shmancy flash stuff. Also, my boss is far too gung ho about having every web page include some form of flash, whether it be and introduction or something in the corner. His suggestions usually mean making the site look tacky or it distracts the user from the actual content (he insists on it even when the clients make it very clear to him that they don't want any flash on the page at all).
