what i think he means is the current Pre-DOCSIS3 kit, he is confusing the pre kit as full official spec, ITS NOT.
"bronze" bonds 4 of the downstream and adds Multicasting,ipv6 etc
and currently uses one upstream, but we are talking a usable 40Mbit/s per stream (for the slower non Euro version)for both the download and the UPLOAD, so its not all bad for now,not that VM will give the user anywere near that usable bandwidth ,justas you dont get to use anywere near the current 1.1 10Mbit+ upload rate.
"silver" adds the matching 4 upstreams,Qos Multicasting, and extra security etc
as far as i know, all the kit VM are trialing are based on the TI Puma 5, a cable modem chipset based on Docsis 3.0, and it appears that isnt designed to do more than the minimum 4 down/4 up channel bonding
but it is designed to have 2 chipsets on the same board, so some form of 8 channel bonding can be made to work in the future IF they/VM see fit to supply/buy in such a dual fitted board (EUE,End User Equipment) CPE (Customer Premeses Equipment) for longer term investment, expansion and savings.
if you really want to see some interesting facts as found so far by me, take a look at the thread

iv put several current (at the time of posting)bits of public info regarding the spec,hardware and so on.
remember though some of that is for the generic US DOCSIS3 not the faster EuroDocsis3 spec that VM will use i assume.
109,113,114 sollp,118toto, and 119 are all relevent when taken together to meet the spec and the reshuffle of the spectrum.
