Ok, here is a dumb question! Would it be possible to have multiple network stack support available as a kernel compile option that, if enabled, disabled other functionality that conflicted with it? I would guess that few people need to have multiple network stacks on their systems and that those who do might be able to accept the loss of other functionality to get this feature. /Ragnar
