Where/how do the proprietary servers come in for a kernel that doesn't want to allow them (and therefore would go through no special effort to make them possible)? Remember that the reason you can link against glibc is because it's LGPL and not GPL. The LGPL was created for a reason. There's also a reason why when the decision was made to release Java under the GPL, Sun explicitly added a linking exception. It's because that isn't something you just automatically get for free.
