Frank and all,
Looking over my post again, I realize apologies are in order. I was pretty bleary eyed as I put it together, and while I edited a bit, it obviously wasn't enough by a long shot. So MANY things to fix for the sake of clarity. Missing words..Better take it slow...Avoid headaches. But I think you'll get my points, by and large. Missed some bolding..ACHHH! And I really am still pretty bleary, so I ought to let it rest a few days myself.
I missed adding a link in the end:

Capacity and tiered services
The S-CDMA Media Access Control Layer (MAC layer) minimizes intercode interference via a synchronized spread spectrum method, thus approaching the theoretical channel capacity limitation. The MAC layer?s cell-based architecture enables multiple tiers of service (guaranteed and best effort data rate) with the flexibility for symmetric and asymmetric bandwidth provisioning. This enables allocating bandwidth for each network modem dynamically, based on service provisioning, priority, overall channel capacity availability and real-time bandwidth use, so operators can offer Quality of Service (QoS) levels to its subscribers.
"Allocating bandwidth...dynamically,... based on real-time use." Just what sort of point might this amount to, compared to TDMA's slowing with greater use/users? I guess it is to explain that S-CDMA's ability to allocate guaranteed minimums and provide, I think, faster speed "best efforts", is based in part, on bandwidth divied around to the many modems as needed, very efficiently? I wonder, if this locks in slower top speeds for most users(as payed for), but guarantees what'll be there, it might lead to implications pertaining to offered content, both good and bad?
