Sorry for the tardiness of my reply.

I do not agree with this; as I've pointed out ad nauseam, this problem was already solved some years ago in Diameter. The current problem is that some folks don't want to accept the solution (though, strangely enough, those same folks seem to be in a rush to turn RADIUS into Diameter (again)).
> * RADEXT WG is the place to solve the problem.
If the first statement garners consensus, I can't think of any other place to do it.

I think that the attribute exhaustion problem should definitely be the focus of the solution for the attribute exhaustion problem ;-). Seriously, I think that one you solve that problem, the solutions to a bunch of other problems will pretty much just fall out.

Hope this helps,
