Read up on cross domain data exchange with SWX Beta 1 on the SWX blog.
I presented a new version of my Rediscovering Fun session at Multi-Mania yesterday and had great fun doing so!
There are two things that I wanted to get in there that I haven't been able to. The first is writing in the actual calling URL to the allowDomain call in the data SWF (so that the application that loads the data SWF doesn't have to System.allowDomain the data SWF just because it has to use _parent._url for its own allowDomain). The second is an API addition. The current beta will have a cancel() method. In the next beta, this will be replaced with pause() and kill() methods.
It used to be $200 per job, which I personally thought was really excessive! Thankfully, Dave updated his Joard job board engine so that job board owners can now set their own prices so I've lowered it to the lowest it allows.
