Well, the Windows DLL hell was a little more insideous. The problem there
were DLLs that had the same name, yet were incompatible with each other.
In the case of Linux .so files, there are at least version numbers that allow
incompatible versions to co-exist.
To wit, I once had my system setup to run a.out, elf, libc5, and glibc
binaries. Basically, I could run any Linux binary ever created up to that
point. It was a gigantic PITA doing it.. but it did work.
So it *is* possible. What is needed for it to be come a reality on a mass
scale is for users to care enough. If enough people made a stink, then the
distributions can start shipping the "compatability" layers. I think SuSE
already does to some degree...
