If a UDP packet is critical then set a flag in your packet header requesting
an ACK be sent back. This will of course mean you need to design a method of
knowing which packets you sent required an ACK, clearing ACK'd packets,
knowing which ones haven't been ACK'd yet, and resending the packet.

Obviously this should not be used to replace TCP, but in the case where you
want to send *most* of your packets to the winds and just require a few of
them to be acknowledged this should work well.
