Craig,
yeah it was easier when I worked for a dot-com :) These days, I work
for an international company (you may have heard of them, it's Sony).
Very rigid in who does what and who has input. Of course, it didn't
help that I started here partway into the process and they had already
decided on equipment. I screamed, they listened politely, told me that
"it doesn't matter, we are on a SAN" and basically ignored me.
