How do you plan for your magic "easy" error/sequence checking for UDP system to be able to avoid this TCP issue? In order to "error check" it will need to ask for retransmits of packets with errors (which will interrupt the steady flow). In order to sequence check it will also have to request retransmits of missing packets (which will interrupt the steady flow, and here you'll get the same queue wait incurred by more recent packets while the retransmit occurs so you can reassemble the original sequence).
