Sorry if I am outright clueless, but it would be very interesting if it can be used for multiarch scenarios.
Multiarch and biarch requite that each coexisting architecture has a distinct dynamic linker.
Maybe to simplify mixing x64 and x86 in a distribution-agnostic fashion, or even more interesting; Not only to run the foreign code but also link to a library of foreign architecture.
This is not possible even with thunking of function calls (very expensive if you have to make 32/64-bit mode switches) as the different architectures have different memory layouts.
