Thanks for your perspective on this; I obviously do not agree (but
that's to be expected - If I had, I would have addressed it already)

There was quite a bit of work involved behind the scenes to make
this happen (but that's likely not apparent)

We've never raised fees, and that's not the general direction that
I've been given in the past by the Board.  In fact, we've lowered
them 4 (or 5?) times since ARIN's inception, and I do not believe
that such has had any impact on our services.  In fact, we've done 
more automation work in the last 2 1/2 year than we've done in the 
history of ARIN, and you can review the development achievements

Acknowledged (although many of us opted for MPLS and fast reroute paths

Please make a concrete proposal for discussion by this community.  It
would be quite timely, since myself and the staff are presently trying
to prioritize the 2012 budget and looking forward to input here and at
the Public Policy Meeting next week.
