I have written a small daemon "lxc-cmdd" running inside the container,
which the host-script "lxc" can connect to.
Example:

root at zoo:~# lxc -l
container              disk (MB)    RAM (MB)   start-PID    status
fex                            -           8        1230   running
gopher                         -           7        8583   running
ubuntu                         -           0           0   stopped
vmtest1                        -           0           0   stopped
vmtest8                        -           0           0   stopped

root at zoo:~# lxc -x fex "uname -a;uptime"
