Cool! It was fun catching all the references. My favorite verse was this one, I think:

So when you're done admiring my resilience:
An engineering feat of flesh and bone,
Please let me sit and bask inside your brilliance.
Remember my design is yours alone.

Which is really very romantic, but it a nicely sci-fi way.

I was trying to figure out the pattern of which verses were from which POV, but I couldn't always tell which were which. So far I've got:
Tony, Tony, Steve, Steve, Tony, Tony, Steve, Steve, Tony, Steve, ?, ?, Steve. Was I close?
