Hello Tom,

on a general note I'm wondering what this offers over the existing SCTP 
support. SCTP offers reliable message exchange and multihoming already.

On a specific note, I'm wondering if the dup(2) familiy of system calls 
isn't a lot more suitable/natural instead of overloading accept.

Best regards.
