Digital Workshop

Just read that Adobe bought Macromedia today ($3.4B USD) in an all stock deal. Article said they could have bought it for less anytime during the past two years...

It was interesting to note the article mentions Flash, Shockwave, Illustrator, even Dreamweaver, but not one mention of Director or Authorware. I guess those aren't considered "main stream" products.

I have a vague idea that Flex is the developers code (SDK?) sold by Macromedia to people like Opus (or Swish etc) to develop their own flash creation apps.
If this is so I wonder what this implies for Opus?

Macromedia provide the specifications for how Flash works - it's up to each developer to write the code that creates Flash files. Opus Flex export is safe; unless Adobe change the format in the future and don't release an SDK for the new format. I would imagine it is in their interests to keep other developers using their products though...
