It's probably more likely that not everyone has as much time as Dave does ;)

What about renaming genrv to any_rv?

Yeah, that's probably a better name.

No, I haven't :(  At this point, the easiest way to write portable code
seems to be to do an ugly "#ifndef BOOST_NO_RVALUE_REFERENCES / #else /
#endif" dance :(  Which I would expect would make it largely inaccessible to
general users, mostly relegating this technique to libraries that want to
provide a more performance-friendly interface.
