hmm no disrespect intended but .. this line of the article jumps out .. "C++ is a good choice for a standard implementation of the protocol, it is a common denominator of most of the languages out there, it has a massive developer community and is widely adopted in the industry for performance middleware applications."

AFAIK the linking characteristics of C++ are pretty bad, since the symbols are mangled in a compiler-specific way, no?

If a small library implements a protocol for any new kernel to re-use, wouldn't it be better to use a language that results in stable external symbols, for linking ?
