Re: [atoca] The future of atoca

Hey Henning,

I appreciate the desire to take on big problems, but I think the abundance of seemingly big questions in this space has actually held this group up.

I would suggest instead focusing on a drastically simpler phrasing of the question: We need to get an XML document to a bunch of devices.  What's the minimum we need to do that?  

Once we have *an* answer to that question, we can optimize it to have other properties, e.g., better scaling through multicast.
