[plug] split dns based on destination domain/cc

[wdk@moriah]

actually, that jogged a memory and I just created a zone called "com" in binds named.conf with forwarders setup - was looking far too deeply into the problem and missed the easy solution.

However, I will probably need dnsmasq when I get further into this project.

Thanks Again, 
BillK

It then takes the first valid answer received and sends it down stream. It makes for _very_ fast resolution if one of those has the query cached.
