I will confess to being in the networking should follow the scheduler camp :)

It is perhaps too speculative on my part, but if the host has no control over 
the remote addressing of the connections to/from it, doesn't that suggest that 
allowing networking to lead the scheduler gives "external forces" more say in 
intra-system resource consumption than we might want them to have?
