Hi all,
There is a framework in ns-3 called Direct Code Execution that allows 
one to run implementation code (C/C++ daemons, and/or the Linux network 
kernel) from within the simulator.  For more details, see [1], [2].  For 
example, quagga has been supported in this manner [3].

There has also been work integrating mininet [4] and CORE [5] emulators 
with ns-3 lower layers.  Container integration has some advantages for 
small network experiments, but the direct code execution support has 
been shown to scale better and has the benefit of allowing one to debug 
a network within a single address space, as described in [1].

Anyway, I thank Andreas for bringing some attention to your community, 
in case it can be of any use.  We have an active forum on 
ns-3-users at googlegroups.com if anyone has further questions after trying 
it out, or feel free to contact me.
