You could do this but you have two major issues with it:
1) It's twice the amount of work. Now you have two websites to maintain instead of one.
2) You risk the search engines considering you serving them up special content and banning for it. I wouldn't say this is certain to happen, but just the possibility of it makes the idea of trying it not very attractive.
The right way to handle this is to place alternative content in the tag as specified in the HTML standard. That way users who don't have flash can see this content instead. You can do a lot of what you want this way without risk of penalty.
If you have an all flash website you have to accept that you will be handicapped in the search engines. It's a trade off that the site owner has to accept when they decide they are going to go with an all flash website.

That is a good idea and i didn't ever think of that. I am pretty sure Bots would see the text because they aren't taking picture of the screen they are looking at your html files so if you have the text there somewhere then I am sure search engines will find out about it.

Also search engines are very fond of quality inbond links though it a flash site, I usually see few top flash sites that has tremendous traffic and rank well in most of the search engine.
That's the only real hope a flash site has. They need to get a heck of a lot of incoming links, quality ones at that, to hope to rank well at all. Flash sites have a slightly higher success rate of getting a successful viral campaign going because of the little tricks they can do with Flash but unfortunately most Flash sites don't really offer that "wow" factor or anything else to get a viral campaign started.
