You can run essentially as many apps as you want inside a single 
container, you just can't start them from the outside.

For a single service or app, run lxc-execute ... myapp

For multiple services/apps, run lxc-start , which will run /sbin/init 
inside the container, and init starts up multiple services the same way 
a regular server does.

You could do almost as much with lxc-execute.../bin/bash, but you do it 
from that shell, from inside the container, not by trying to run 
lxc-execute multiple times to create multiple processes.
