Wherein lies the problem (after spending 26+hrs in a data center upgrading our network and virtualized server environment...); it has to do with the demands of hardware interface and servicing the stream based on a serialized and interrupt-driven environment.  Audio service, at the analog to digital transition point, is intolerant of the CPU being off 'elsewhere' or managed as part of a pooled resource (simplistically) in a highly loaded environment.  Hubs, etc work fine; but, when you get down to the nuts and bolts of actually doing hardware control, audio processing, etc, you really want a direct processor/memory/I-O capability.  

Besides..computers that you can dedicate to the task are not the most expensive investment in a radio/repeater/etc setup.  Because you can do it does not necessarily mean you should do it..:)
