I see two parts to what you want: (1) various link technology
protocols, and (2) optionally a more restricted control protocol to
reduce the probability of error propagation, etc.

Looking at these separately:

(1) Generally TRILL over X link technology stuff gets done in the X
WG, if there is an X WG, not in the TRILL WG. For pseudo wires, we
have agreement from the PWE3 Chairs and AD that it should be done in
TRILL as long as there is not change to PWE3. For IP, there is no IP
WG. I'm not convinced we could get something that would imply we could
do TRILL over an WAN technology approved in our Charter.

(2) You might want to run the currently specified TRILL protocol over
a WAN link or you might want to run a reduced control protocol. This
is mostly orthogonal with the link technology. We already have the
current TRILL protocol and doing a reduced protocol is a separate item
in the draft Charter.

So, for the above reasons, I think the draft Charter item is reasonable.

Drafts mentioned in the draft Charter are just supposed to be
examples, not binding, and could be dropped.
