Sadly, there's a lot of stuff that will break DNS especially to things
not the default DNS server you get from DHCP.
There is  an implementation of IP tunneled over DNS--not just the port,
but actually in a DNS protocol that will work even if there are
recursive resolvers in the way.
It's performance is not ideal:-)

I've certainly seen a lot of protocols look at the HTTP encapsulation
route.  These days you could potentially use web sockets.
