I'm late but whit any decent HSI connection you should be OK in a home environment to run an internet radio station and do most anything else short of a huge, unrestricted download.
In an office environment, sometimes it's just not the Internet bandwidth that is the bottleneck but all the other traffic floating around on your network that is taking up space. It all depends on how well it is configured, switches vs. hubs, intelligent routing and design, etc.
Using my pretty meager 5MB connection (country living) I'll have an internet radio station playing on the Squeezebox, run my works stuff via a VPN to my work, chat with co-workers over VOIP and download a decent size file from our work servers and never hear a hiccup on the radio feed.
I might even have the Axiom board up on my second monitor but that uses almost no bandwidth at all, except when Peter and Ken are spamming the heck out of the ShoutBox. heh heh.
