Personally I'd stick with the default veth-on-bridge setup.

You mean the default lxcbr0 setup? AFAIK it's there to make beginner's
setup easier, i.e. it would work even if your default connection is
wireless. This is different from xen, where the default used to be to
create the bridge over eth0, thus making the vms appear on the same subnet
as the host. which would not work for wireless.
Of course, you can always change the defaults. Some possibilites (for any
vm environment, including lxc, xen, kvm, etc):
- inter-guest only networking
- guest-to-host only networking
- guests on a dedicated subnet, with NAT to outside world (the default with
lxcbr0/virbr0)
- guests on a dedicated subnet, accessible from outside using host as router
- guests on the same subnet as host
- guests on a different subnet/vlan from host, and directly accessible from
the outside world
etc.
Basically if a network configuration can be implemented using L2 switches
and routers, it should be possible to implement the same configuration in
lxc guest-host setup.

That's easy. Either put guests on the same network as host, or (if you have
control over the network) use vlans and treat the host like an L2 switch.
