Yes, having a customizable/pluggable network stack sounds very useful.
In general, OpenSource projects like Linux don't give much incentive to pluggable designs, because the source, being open, represents a weired form of pluggability. Unfortunately, this "hack it up / code it hard" design style usually inhibits healthy development.
A rethink is probably in place...
Thanks!
