Therefore there will only be around 8.5Mb/s useable bandwidth available to all 50Mb/s & 20Mb/s customers located on the bonded group.
If much higher upstream speeds where provided it would likely lead to upstream congestion..

Could be improved and was set to be improved, i'm sure you are quite aware that money was going to be pumped for said upgrades to allow 5+Mbit/s upload speeds on the 50Mbit tier as per the original trials.
But as per usual within VM, opt for the cheap and nasty, screw what the customers want.

In my opinion they would be able to support 2-2.5Mb/s upstream with the proposed implementation.

2.2Mbit to be exact and was seen as not viable, not set to change.

It is my understanding that contrary to what Traxdata2 says VM have not yet entered the 'Product Trial & Pilot' phases yet.

Your understanding is wrong then, you seem to be wrong quite abit zenith as per your postings on digitalspy.
3 New areas were enabled to move onto pilot phase just over 3 weeks ago, working along the team with alex you of all people should know this.

In my view they will look at the trial and pilot data with regards to upstream channel utilisation with a view to tweaking the upstream and going forward they will be looking at ways to improve upstream speeds (QAM32/64, 6.4Mhz Channels, SCDMA on <20Mhz spectrum, channel bonding etc)
It is not beyond the wit of VM to blow the competition out of the water with respect to upstream speed.. It just has not been in their focus over the past few years.

They are not looking at ways to improve the upload/upstream speeds as "alex" believes customers do not want nor need it and as most people who are with VM are not close enough to an exchange to get high upload speeds from ADSL2 they dont see a point until competition can force them.

I have it on good authority that this is about to change

Funnily, no one in the network planning department thinks this, so one has to wonder where your info is coming from?
Alex also has no idea about this and he is head of the department
