Universal Binaries for Linux

Ryan has launched the FatELF project page where he talks about how with this file format it would be possible to make a universal Linux installation DVD that could automatically handle both x86 and x86_64 systems (or even PowerPC, MIPS, and others too), support for shipping a single shared library, support for kernel drivers targeting different architectures in a single file, and there's a whole range of other possibilities using FatELF.
