I work at Axsh (https://axsh.jp) and that stuff is exactly our thing so 
I could always put together a presentation. Disclaimer: We don't really 
use (Kubernetes, SDN/NFV, OpenStack) and have our own in-house (but open 
source) solutions instead. (OpenVNet, OpenVDC, Wakame-vdc) I don't 
really have much experience with the more known software suites like the 
ones you list but I could say some more generic stuff on the topic or 
give a demo of some of our stuff.

We're also working on this network switch, Linux box hybrid that 
basically gives you an environment in which you can design virtual 
topologies and then plug in physical devices like firewalls, routers 
etc. into them. The main use case we're looking at is automated testing 
of network infrastructure. I could bring one of those hybrid switches 
and give a live demo.

Or if TLUG doesn't work out, you're also welcome to drop by our office 
for a beer and a demo some time. :)

Sounds like we're in the same boat on that one. It could be a lot of fun 
to work together. For example we could take 10 minutes to explain Sonic 
Pi itself and then 25 minutes each to show off some of the music we've 
written in it. Hopefully our results will be radically different but 
both cool in their own way. :)

My experience is that the hard part is really setting up JACK and that 
gets easy once you know how to do it. Basically install the qjackctl 
frontend, click on setup, select your soundcard under Interface, set 
sample rate to 44100, adjust Frames/Period until the latency is about 5 
or 6 msec (I had to set it to 128 for this), set Periods/Buffer to 2, 
click ok. Now click Start and things should work. This must be done 
before starting Sonic Pi. While JACK is running, PulseAudio will not be 
able to play anything unless you do some more setup.

OR... just get a Raspberry Pi and install your standard Raspbian. It 
comes with JACK all configured and Sonic Pi just working. Sonic Pi was 
actually made for Raspberry Pi originally, hence the name.
