What is the implication of what you are saying? That the proposal i've put forward is wrong or that the concept of diasy chaining is fine provided nobody controls it?
For me, the reason tier 2 is workable, is because I can view a small number of new drivers and check they are ok, the existing tier 2 drivers can report issues, having 200 drivers in two weeks is a lot more manageable than the 3500 connections to the tier 1 public servers.
In terms of control and power, I can on my own servers say to a driver - ok, you're not ready for this, but you can race server 1 - in terms of the practical application this hasn't happened yet because server 2 is a nicer environment to be in. This is all fine and dandy.
The problem comes if I could retain this ability, and be expected to administer this ability, on other servers. If server admins look to me to penalise drivers for their infringements, we get into the sticky muddy waters that I want to avoid - which is why I would only be happy for other servers to have access to the STCC license system on a non-update basis - no progress, no regression.
EDIT: But I am more than happy for them to maintain their own license system.
EDIT2: Likewise, giving server operators the ability to interlink licenses not only creates confusion over what licenses are required to join what appears to be a public server - but also gives other server operators the ability to effect the membership of other servers.
