I wasn't thinking "dedicated" from a HW perspective, rather more like 
Galaxy, where the OS or something could automatically or be set to 
assign cores to specific tasks.  Could be a lot of flexibility with 
something like that.

Some people might be doing no network activity, and, some people might 
be doing mostly network activity.
