I would also like to work on this.

I find the idea of trying to identify a meta-profile intriguing. In
addition to the superset and subset profile motives that Mark identifies,
it seems to me there is also the motive for defining profiles that
provided increased, or more predictable, interoperability. Inherent in
such a motive is the perception that industry segments, e.g. TV, demand
better interoperability than is achieved in the Web today. I'm not sure I
share this perception but it be useful to see if it could be quantified,
i.e. what are those specific areas.
