I just saw this article about an effort to create Universal binary style ELF
binaries for Linux, and I thought that this would be something to watch, so
that Fedora could integrate both x86-32 and x86-64 into single DVD sets.
There is even a proof of concept VM of Ubuntu 9.04 that has both 32-bit and
64-bit kernels and all the apps compiled as FatELF binaries
