There's no free lunch; what you suggest (if I understand correctly) is trading time slices of a broadband transmission for frequency slices of a time-continuous transmission. I think the horses mouth here would be Shannon and those old chestnuts. Thing is, each host would have limited bandwidth. You'd have to make sure that in doing so, each host had all the bandwidth that it previously had before, which means designing a new transmission system with higher bandwidth than you had previously. There's no difference between a transmission system that goes faster and one that goes wider -- think of it as an area problem. Pulling on one side shortens the other. Anyway, now you're getting back into analog electronics -- impedances, freq response, etc... Fun stuff, but not really what you were hoping to do, I think.
