I'll rephrase: why is any new VM to be relegated to the OS? The presence of incumbent VMs?

JS is an incumbent. Pepper is similar to nsapi, and has nice features which are compatible with HTML5's implementation (as in canvas). Saying it shouldn't be adopted because Nobody is adopting it is circular.

What are old-style plugins? Anything not JS?

Why differentiate plugins? What makes a VM with JIT not a plugin save the browser vendor shipping it with the browser?

Why wouldn't other browsers have Pepper?

Compilers are as good as what they've been tuned for. In my view PNaCl's shortcoming is startup time because it lacks a JIT and LLVM's back end is too slow for now. Speed up the backend or JIT code and you'll get close to GCC performance while being portable and somewhat language agnostic.

Yes I have seen pepper, and most of the interface relates to the GPU. How is sunk cost better, when a big part of the API can be backed by what canvas relies on?

You would consider adopting PNaCl and pepper in FF if there were games that targeted them? If the code were contributed to Mozilla?

What do you mean by "more native code"? Can't view source?

I appreciate the answers.

These are shallow arguments: * pepper is "inspired" by nsapi, clarify your point. * PNaCl performance lagging isn't a solid argument, you know it'll get better, the solution might even be to cut LLVM out save for bitcode. * "nobody does this at the moment" so why does it belong in the OS?
