SWFAddress it's very cool way of providing deep linking in flash. But unless you use #! in urls (and a other things too), google wont index your internal pages.
How would be the best way to configure (or modify) SWFAddress to use #!?
I actually found the answer in another question here in stackoverflow. I want to post the solution for future reference:
Just open swfaddress.js with your editor and replace all instances of "#" (with quotes), with "#!". Is that simple :)
