Not necessarily. If it needs access below what the socket layer can
provide, then sure, it needs to be in the stack. But if what sockets
do provide now, for UDP and TCP, is usable, this could be done inside
a library.

They managed to make a library implementation of SCTP (another transport
layer). Granted, it is limited to user processes with root permissions.
Is what you are doing also at the same level?
