Sure ... they can end up out of order -- UDP doesn't guarantee delivery, and packets
may arrive out of order or duplicated.  (Of course, this shouldn't happen on the *same*
host, but .... !)

May I ask why you're not just using IPCs, since that's what it sounds like you need?
UDP is usually used for self-contained data (like in XDMCP) and as the basis for a
more complex protocol (like TFTP).
