So we don't need completely arbitrary fat binaries at all: we need a 'fat dlopen()'

To solve this particular problem, yes. But then Ryan's FatELF release supported dlopen()ing fat shared libraries.

Yes, but if that's all you need to do, the kernel side of FatELF is superfluous.

Oh agreed, and in this particular case, it's not necessary. However, there are other situations where full fat binaries might be a win. I just get extremely annoyed by people claiming that the whole concept of multi-arch binaries is useless just because they happen to not have a valid use for them, and are unable to see that others might have.

The attitude appears to be 'distributors don't need them therefore they are useless'. This seems, to me, more than a little shortsighted...
