APR: Considering that before we know it, http/2.0 will be here, and ignoring httpd for the time being, what features/additions do we see as being needed to support http/2.0 from an APR library level? How do we compare w/ libuv, for example? How "event-aware" should APR be, ala libevent?
HTTPD: From the httpd point of view, what does serf provide for us to help us get to http/2.0? Should we make it a requirement? Are there things we need that, instead of making them part of httpd, should really be in APR instead? What other external libs should we be leveraging?
