Some people have implemented simulation-type transport elements. Look for
TCPConn, TCPBuffer, and so forth in elements/local. We didn't really design
Click for this (other networking component systems, like the x-kernel
and/or Scout, might be more appropriate), but I'm interested to know your
intentions. Why do you want to implement TCP/UDP/RTP and sockets in Click?
