Depends on the format of the interview, if it's live, ie. in a chatroom or something, or over MSN (I don't think they will be phoning up) there is no reason why more then one person can take part, and if its in the form of an email with a list of questions I can't see why you can't forward it on to other team members asking for suggestions for answers to be posted back to you in 24 hours....

I'm not saying everyone needs to take part, but its a great way to make sure all the information is correct and useful! You know alot about the historical battles that will be included in the demo, I know alot about how we are working within the confines of RTW re. model limits and gunpowder.
