We could have a site that queries all in the list for your address on the api port.

Edit: I've set up a SRV record as an example. _bb._tcp.us.cncoin.farm that has all the pools listed on the first page that have dns names for connecting. That is one issue with this approach. All pools would have to have a name and not an IP for a SRV record to work. You can see what it returns with

in linux, or
in windows.
example output:

Notice it gives a port. It has a priority that I have set the non-us pool to a higher number to give it less priority. Could do the opposite with a _bb._tcp.non-us or _bb._tcp.eu or whatever, even separate lists for cpu/gpu ports. Obviously, it should be managed by core boolberry team or at least not a pool operator, and then miner would have to use something like libsrv (first google hit I saw) to query this record. We could even have a complimentary SRV record to determine API port of these servers I guess. What do you think?
