A longer charter should not be a goal. You only have to cover the basic points:
Some networks require some form of interaction from users prior to
authorizing network access. Prior to granting that authorization,
network access might be limited in some fashion. Frequently, this
authorization process requires human interaction, frequently to either
arrange for payment or accept some legal terms.
Currently, network providers attempt to reach a human user by
intercepting cleartext HTTP to force a redirect to a web page of their
choice. This design creates a number of problems, primarily: it can
only work if an endpoint initiates a cleartext HTTP connection, and
the interception looks like a MitM attack.
The human eyes needed to access Internet (hmm, maybe your name is
better) working group will define mechanisms that:
- allow endpoints to discover that they are in such a limited environment
- allow endpoints to learn about the parameters of their confinement
- advertise a location whereby human users can directly engage with
their captor in order to obtain unrestricted access
- (optionally) advertise a service whereby devices can enable or
disable unrestricted access without human interaction
On this last point:

The problem with this last one is that it is unclear how endpoints and
network come to agree upon the terms under which a request of this
form is authorized. I've not seen a clear model for that, and I
wouldn't want to have one before addressing the more pressing issues.
