I'm using a Draytek router/switch for my connection with the Internet.
It has the possibility to limit the traffic on any of the four switch ports.

Sorry, I should have been more precise.

It has the possibility to set the Quality of Service. For instance I can
set a rule whereby I reserve 75% of the outgoing bandwith for HTTP, so I
have 25% left for other things. Is this what you are looking for?

I was wondering about that concept too, hence my Linux/DSL bandwidth
management/QoS reference earlier, but I happened to be looking at DSL
routers yesterday (my D-Link DSL604+ is showing its age) and it seems like
QoS stuff is no longer confined to higher end or DIY Linux routers. A GBP40
SoHo router from Billion (7300G) apparently comes complete with
flexible-looking QoS, SNMP management (but no DSL Line MIB), and even
something it calls VLAN support. Whether it actually *works* as marketed is
a different question, but on paper it looks good. Other boxes at similar
prices also seemed to offer QoS but I didn't look in so much detail.

If upstream bandwidth saturation due to other folks downloads of the audio
is the basic issue in this picture (we don't know that for sure yet), a DSL
router with decent QoS capability could be a nice simple fix.
