The proposal that roc and smfr put forth is this: Native code could call Web APIs, slightly tweaked for the benefit of native code and to satisfy the security/isolation guarantees that Chrome wants to enforce. These same APIs would have JavaScript versions, so that ordinary Web content could use them as well. For example, the same asynchronous 3D command stream API that Pepper exposes would be available to Web Workers.

Here's some further reading:

Note that Darin's followup message included this:

"I do agree however we want to keep Pepper APIs in sync with existing Web APIs. That will obviously be a challenge if they are not one and the same, but I don't think it is impossible or even that difficult to achieve with them being separate APIs."

This has already failed. Web Workers cannot render even 2D content asynchronously today, while Pepper can (which advantages plugins and NaCl over ordinary Web content). This is exactly the problem that roc and smfr were trying to avoid.

I don't think that Darin's example, of an <embed> tag being untouchable by Web content, is an insurmountable problem. In fact, I think this is exactly the kind of thing you want JavaScript content to be able to do -- high-fidelity JS versions of PDF and Flash would be great. And the issue of Web Workers and audio APIs needing shared memory is a Chrome problem (because Chrome puts each worker in a separate process), but not a problem for browsers generally.

Also, the argument that "it's an existing plugin, you don't want them to rewrite their code" doesn't hold water. It's an entirely new set of plugin APIs. Adobe has to rewrite its code anyway. It's just that the other browser vendors wanted the Web as a whole to benefit from this, not just Adobe.
