Interested for sure, and I suppose a quick 3 things I've learned from NRPs in the past:

 - Prevent early fatigue and morale drop by preventing over-saturated character sheets and oocs. Get the info needed, get the meat of the what the nation is about and how its society/culture is structured, and then get to RPing.

 - Prevent people using deus-ex-machina devices in order to prevent character death or perceived situations of "loss". This mean either using a point system for military, tech, and economic factors or by just being a more hands on GM. 

 - Last but certainly not least, begin the role-play based on precedent that it is first and foremost a STORY and that people die and lose in STORIES. Not everyone needs to win all the time and not everyone needs to lose all the time. This can prevent a lot of needless heartbreak and will attract only those roleplayers who are truly interested in telling a brilliant story.

That's really it. And yeah, definitely interested.
