I've thought about UDP but don't want to incur the overhead of making sure the
packets are delivered reliably, in order, etc. Also, with UDP isn't there router
considerations if running over a WAN ? The application I am writing must handle
heady I/O load and be reliable. I was thinking that one could add a thin driver
to intercept TCP writes and handle the many send there given the appropriate
target IPs by the user application.
