Pie chart is a good idea for that one.  Even better if it was a cake chart.

For the "evil" host, I recommend a gaming PC downloading an update through Wargaming's launchers (World of Tanks/Warships/Warplanes).  I believe they use libtorrent, but practically all of the bandwidth is supplied in practice by "web seeds", and the active flow count per downloading host is typically in the hundreds, each to a different IP address in WG's CDN.  At that level, end-to-end congestion control simply does not work without network assistance, which Cake happily provides.

Another local host could be running a videoconference session to two or three remote callers simultaneously, while a third simply downloads something with a single stream.
