FWIW, I *like* that lxc doesn't force its own idea of how to do
e.g. network configuration down my throat (cf. libvirt, vmware-server).
i.e. LXC sits on top of my distro, rather than my distro having to
accomodate LXC's way of doing things.

Ditto.

I believe this works (Debian/Ubuntu flavoured):

    lxc.mount.entry = /etc/lxc/foo.interfaces /srv/lxc/foo/etc/network/interfaces bind,ro

The RH equivalent would be file(s) within /etc/sysconfig.
