Resolution for photo libraries: Heads up!

I've been on the verge of lodging a bunch of shots with a prominent Australian photo library as they were very keen on the strength of my tranny portfolio. I've been very happy with the general quality of my D70 images and 'pixel-peeping' resolution limitations hadn't even entered my mind.
I've been happily shooting away in RAW format, secure in the knowledge that I can interpolate pretty well up to 71.8mb at 8-bit RGB with the Adobe Camera Raw plugin, when I recently heard back from my contact that "We require 50mb hi-res files - not re-sized to 50mb..." and "I have put on the web that I will start looking at 8mb cameras but have found that they are not always ok for all uses so I may change this. Which camera are you using?"
Well, dang me. I must confess I haven't responded to this just yet. Several people have responded to Sheepie's fabulous POTW that it's worthy of National (or Australian) Geographic, but apparently if you haven't shot it on transparency or aren't capable of supplying a 50mb uninterpolated file, this particular photo library at least won't accept it.
Has anyone else encountered this kind of stonewall, or is it just me?
If so, maybe I'll just go back to fingerpainting
