>Since Chromium doesn't support flash (that is one of the closed source bits added to Chrome)

The Chrome PPAPI Flash Player works perfectly on Chromium and the binary can be shipped separately.

In principle, but does Adobe ship the Flash PPAPI binary separately?

[gcr]

How do other WebKit-based browsers like Luakit get flash to work? I thought they were always using the NS Plugin API for Flash. Is that being deprecated; is PPAPI a replacement?

[gsnedders]

Adobe no longer support (except for security updates) the NPAPI (not NSAPI) plugin on Linux, which also has a habit of crashing a lot and randomly hanging… If you want Flash to work under Linux, one practically has to use the PPAPI plugin.

Note nobody except Chrome (and those based on the Chromium Content API) has any plan to support PPAPI, so in that sense NPAPI is alive and strong.
