It's always a good idea to have at least two nameservers configured for any public domain, and best practice involves having nameservers located on different networks. > If for some reason I have 2 of them and one is configured to point to SERVER > A , and the other to SERVER B.

No, DNS round-robin used on most platforms will rotate fairly evenly. And the traffic can be cached by other nameservers for a long(er) time by upping TTLs, if you wish to reduce network traffic load...at the tradeoff of making DNS changes take longer to be noticed, of course. Bigger sites might adjust DNS traffic onto server pools with a load-balancer which does liveness checks of the nameservers and could be told to adjust traffic routing in various ways. You can also do something similar via ipfw/natd's redirect_address (see RFC 2391). > b) I am looking for good list like this one for people developing, learning > about Android Development.

Hmm. http://developer.android.com/sdk/index.html suggests that maybe the Linux distribution under FreeBSD's Linux emulation might be a possibility.
