Well, can it be both? 

I'm generally curious about them, and how they differ (due to the setting) to real life ones like Blimps and Zeppelins. Would they work along the lines of Guns of Icarus (A fun game where you get to pilot steampunk airships to do battle), or do they more closely resemble reality in the way they work?

But yes, this and everything you mentioned is of great interest to me.
