So we have had a number of threads, some about possible work, some
about details in the charter, etc. I think it is great to start
thinking about a possible charter if this work turns into a WG, and
some good reference drafts (thanks to Qin and the folks from Apple for
putting these together), but I think another way to look at this might
be to at least initially take a step back and see if the folks on the
list can take a stab at some more basic questions. I think that was
perhaps what Qin was getting at when we started this thread, but it is
always good to refocus.

I'll ask two really basic questions to the folks on list, and let's
see what the opinions may be, and maybe we can move forward from
there. Personally, I think that if we have a bar BoF, focusing just on
these two basic questions (ok, one is a compound question, but one is
basic!) might be a good way to move forward. I expect we'll have some
VERY different answers. Remember that HTTP streaming may mean
different things to people, and might even be the wrong term...but
these are the things we need to try to figure out.

So the two big questions:

1) On the topic of this list/HTTP streaming, what do you think is the
problem/problems/scenario we should be looking at?

2) What other standards body work in this space are you aware of
(including IETF work), and how do you think any new work would fit in
(or not!) with the answer above?

Yep, these are really broad, but to me, they seem to be at the heart
of what we need to figure out to move forward. I think that at the
beginning of this thread these were the basic questions Qin was
looking to answer, and I think they are a great place to start.
