Having failed to find a convinient solution to get both bookmarking/deeplinking and getting the browsers back/forward buttons to work I decided to put together my own system and make it publicly available.
If you make complete Flash sites you should really IMO include that functionality.
It’s very handy for users and if you don’t the HTML fanatics will get aggrevated 
So get the download here and implement it on your site now!
Suggestions for improvements, reports of browser compatabilities/incompatabilities and questions is very welcome.
