Yesterday, Google announced its intentions with HTML5 and took a dig at Apple’s later adoption of the HTML5 spec: “I think it was a late night Steve Jobs email or something,” mused Google’s Vic Gundotra. Adobe followed with a Dreamweaver and Flash export to HTML5 tools demonstration.

Google announced a new video format called VP8. Adobe announced support for it. (Apple, of course, is behind H.264.)

Google Mobile ads can use Flash for rich media. iAds was introduced by Apple to do the same on iPhoneOS.

Chrome Web Store comes with Adobe Flash DRM support. Direct jab at Apple’s proprietary, curated App Store.

Today, there was non-stop Apple bashing with Android platform numbers weighed against Apple’s iPhone sales. The big announcement? Google Android with Flash. (The iPad and iPhone lack it.) Google TV?  Flash-capable.  (AppleTV? Not-so-much.) You get the picture.

So is the Google Adobe relationship a result of the “enemy-of-my-enemy-is-my-friend” syndrome, or is this just a case of two companies having a lot of synergies?

Both. However I think this bold relationship is going to be a short-term alliance based on a mutual opposition to Apple and a mutual need to differentiate in the short term. Here’s why:

Google is interested in a free and open web based on open standards. They proved that with their HTML5 demos. Adobe builds HTML5 tools, but they really want to push their Air and Flash platforms, which give Adobe an advantage over other media creation tools.

Adobe can’t make money on unwrapped VP8 which Google, Mozilla and Opera are pushing for the future of free web video.  But at the moment, Flash is the best way to get immersive, interactive video content on the web. As HTML5 video tools grow more robust however, Adobe’s Flash and Air become more expendable.

Me? I give the relationship two years before things start falling apart.
