use only sysctl and no kvm (implementing /dev/mem for a rump kernel would probably not be hard, but still a non-zero effort). Note: since there is absolutely no network activity in a fresh rump kernel, rump.netstat usually displays exactly nothing when invoked without parameters. Arguments like -r, -bi, -p icmp etc. produce more stuff.
