Please disregard that last configuration. I have gone through and
enhanced the config based on some more studying. If anyone would care
to comment on the current configuration I would really appreciate it.
It all works as designed, I am really just looking for any 'gotchas'
which I haven't accounted for... as well as anything I am doing which
is very inefficient or otherwise bad practice.
Thanks!
