It's not really about working everywhere. It's about providing the existing browser vendors their own parser, and reference implementation to help promote implementation. It's a small well constrained subset of what they already have. And just now have to provide a compiler for. Not trivial, but significantly easier then implementing the PNACL spec. The LLVM bitcode spec itself is large enough to ward of a second implementation.
