Having dnscache and dnscachex both seems like unneeded duplication.


Options:

1:  run dnscache on the external interface, and make local
programs use the external interface instead of the faster local
interface.

2:  alter dnscache so that it can bind to both the internal and
the external interfaces.

TCP servers can do this.  Is the problem that a UDP server cannot
do that because the recvmsg function does not tell you which interface
the packet arrived at?
