[Users] RDMA capabilities for HTTP

[Weiny, Ira]

Depending on the complexity of your http software[*] you might look at rsockets.

 [*] rsockets does have some limitations in what sockets semantics it supports.  But I know that Sean is very interested in having those fixed if your so inclined.  :-D
