My email was to rebut Dan's implicit claim that PNaCL and using LLVM as a portable IR is never going to work. I'm arguing in the "opencl" and "pnacl" folks favor :)

I think you're overreacting here. There is nothing about OpenCL, RenderScript,
or VMKit that requires LLVM IR be used like a Platform, as I defined it in my
first paragraph. I'm aware that some people would like to use LLVM IR as a
Platform, and I'm saying that there are important high-level considerations
to make before doing so, and my impression is that there is little discussion of
issues I consider important.
Possibly it's too late for some though, and possibly people are getting too
caught up on the thorny ABI issues and missing my broader ideas.
