I'm not sure why you make this assertion... a new protocol family for
SOCK_STREAM sockets seems far more likely to be accepted upstream than
adding support for multiple networking stacks. For example RDS was
recently queued for 2.6.30 as a new protocol family. I have a hard time
imagining multiple IP stacks being accepted upstream on the other hand.
