Virgin claim the whole point of stm is to stop the minority (something like 2%) of users from negatively impacting network performance to the detriment of other users. What you suggest goes directly against that philosophy atm. They have capped you because of the volume of traffic you are generating, especially on docsis 1, and uncapping it and actually prioritising the traffic screws things up big time.
You have lead us to a very good point though which many of us have raised before. Technology has got to the point now where even the slowest of connections are fast and like many users have argued, what do you need more than 1mb/sec for? The OP shouldn't have to upgrade to 50mbit or 100mbit to be relieved of stm when the speed he is getting atm is more than sufficient. I think it would be a great idea for all the tiers is there was a level 1 and 2 where 1 is the more expensive and un-stm'd and 2 is cheaper and stm'd. As an example (I don't know how much 10mb is so this is an example).
10mbit unmanaged on docsis 3 for £15/month for peeps like the OP for netflix and whatever else
10mbit managed with stm on docsis 1 for £10/month, designed for light/moderate use (like it is now)
Both offer you respectable speed which everyone is happy with however they are designed for different usage patterns. I would say you could do the same for up to 50mbit however I think anyone on 100mbit would argue that they want the speed because they download tonnes and want it done asap so they wouldnt be interested in paying less for thresholds to be impossed which would only screw them over.
(I am charging 10% commision on the above idea
)
reminded me of this:
