During the DPRIVE meeting in Dallas, several questions came up about UDP versus TCP.  We had previously submitted a "DNS over DTLS" document which predated DPRIVE.  We re-submitted the document with a few edits and a filename that makes it easier to find, https://tools.ietf.org/html/draft-wing-dprive-dnsodtls, diffs at https://tools.ietf.org/rfcdiff?url1=draft-wing-dnsop-dnsodtls-01&url2=draft-wing-dprive-dnsodtls-00

The working group may want to consider the advantages of DNS over DTLS over UDP compared to using TCP:

 * No reliance on operating system support of TCP Fast Open [RFC7413] to achieve same number of round trips.
 * Avoidance of TCP's network head of line blocking.
