Is it possible to create a binary extension that can run on Chrome OS?

Question

Chrome supports binary extensions on all platforms. But I cannot decide whether Chrome OS supports them too...

Answer 1

Nope, they are disabled on purpose.

See this, this, this.

Answer 2

They don't support NPAPI, but they do support the new native client architecture NaCL.

If your binary extension uses PPAPI rather than NPAPI, it will definitely work on Chrome OS.
