Acrobat.com has hosted Buzzword (a Flash based online word processor and collaboration tool) for a while now. And more Acrobat.com tools are on their way. Acrobat.com Labs is now offering sneak peeks at Tables (a spreadsheet) and Presentations (create presentations, duh!).
Acrobat Technical Evangelist Joel Geraci has continued his series on Flash / Acrobat integration with a new post entitled Saving the State of SWF Content in Acrobat 9.
Acrobat 9 supports the embedding of Flash/Flex based SWF files within PDF documents. In addition to supporting SWF playback, this capability exposes functionality found only in Acrobat, as explained in this post by Acrobat Technical Evangelist Joel Geraci.
