Exactly. It would be great having a local source server (on the host or
on a virtual machine), to not strain your public server and have a
reliable source (on the university's network the connection frequently
drops, which alters test results).
Do you just need the VLC command, or do you have to run Icecast as well?

Thanks for merging. :-)

Now I added documentation to the nts_doc branch, it can be found in the
repo [1], [2].
Also I created a wiki page where I can keep progress and todos as they
show up, to not forget planned tasks, see [3].

Have a nice weekend,
Max

Thanks for the hint. Looks really ancient. :-) Inkscape is a great software.
SphereSim is a project around live molecular dynamics and gravity
simulations. An enhanced version is in development where several servers
can be connected over a local network, to combine computation power. P2P
connections over internet are planned as well, though low latency is
crucial for live simulations.
