Yes, I would like to see the development team add support for dynamic DNS.
To take advantage of traffic prioritization, the Obi202 should be the first device connected to the cable/DSL modem and act as a router, that is Modem---Obi202---WifiRouter---Home_network. That is the main reason why the 202 was developped, to act as a router.
However, as long as dynamic dns is not supported within the Obi202, I will not be able to connect the Obi202 first, and in my case I could/should have bought a Obi100 instead...
