I'm a major proponent of keeping things tidy.  The available budget is
obviously something that the employer has the last word on.  In my
defense, it should be noted that, for the most part, I inherited the
administration of the current network, and am trying my best to fix it
where needed.  Given the unalterable history of the way that this network
_was_ set up, I'm trying to find ways to develop it into a network that
adheres more strictly to the way that networks _should_ be constructed,
and hence, one that you would probably approve more highly of.

That being said, concerning your statement about the two networks:  Is
asking for two /20's instead of a /19 something that ARIN is likely to do?
Or am I misunderstanding you?

Sincerest thanks for your input,

Rick Kunkel
