i guess, but then it couldn't use accounting on the IP level for that
traffic. UML *does* support hostfs, which is wicked cool! so i'll use
that for all partitions that i mount into the VM that aren't to be
accounted. /usr for instance, and /usr/local. and /home.

sure, but then their DNS traffic wouldn't be accounted. that's why their
servers should actually answer. but in the end, DNS isn't a lot of
traffic (if you're not a root server or otherwise big, and if you didn't
screw up your SOA, so whatever... i might just ignore that.)

yes. that and HTTPS. oh well...

me neither. word up! all it requires as root is a kernel install and a
couple of configs like NFS (or coda). the rest is user-mode. i thought
that the host kernel has to be majorly enabled, which would have been
dangerous. but all i need it the TUN/TAP module support...
