It's entirely possible that I was mistaken with regards to /19 vs /22,
but a /22 is still way more ips than I really need, I mean hell, I'm
not really using my /24 currently. I don't nearly have 256 machines,
and I certainly (without honepotting almost all of it) justify 1,024
ips.

In fact, in my network infrastructure currently, I've got one
loadbalancer that sits in front of 6 machines that don't have public
ips, so there goes any thought of justification ;-) and yet, when I'm
at 4 load balancers, I'll want them in geographically dispersed
locations, with a variety of upstream providers so that I don't have
to deal with the issues surrounding single-homed networking.
