the Flash Player browser plugin for Linux will only be available via the “Pepper” API as part of the Google Chrome browser distribution and will no longer be available as a direct download from Adobe
> Because of this work, Adobe has been able to partner with Google in providing a “Pepper” implementation of Flash Player for all x86/64 platforms supported by the Google Chrome browser. Google will begin distributing this new Pepper-based Flash Player as part of Chrome on all platforms, including Linux, later this year.
It says that the plug-in will be bundled with Chrome, and Adobe have said they won't be releasing more Flash players for Linux, but the announcement does not even hint whether a stand-alone Pepper plug-in will be available from Google. I hope the Chromium blog will clarify this in due course.
I guess Adobe might forbid Google from developing a plug-in, but I don't see why they would want that, seeing as they have been distributing plug-ins for years. If Google could but didn't, that would make them look unsupportive of Chromium.
