Ask HN: I'm talking to a potential investor tomorrow. What should I ask?

One of my users of FolderBoy is an angel investor (http://www.dnjournal.com/cover/2009/february.htm). He likes my product (obviously, he’s a user), and he wants to see if there’s a good investor-hacker fit. What are some questions I should ask? And what are some points that I should nail? Considering he already sees the merits of FB, I was thinking: * The direction I want to take FolderBoy in the next 6 months, year, two years, five etc. * Finance and business advice requirements in the next 6 months etc. * His interest in the personal-organization space What else? Also, one catch: he’s in the US, and I’m in Australia. If things go well, I will need to meet him at some stage, how would I broach the subject of travelling over to the states? E.g., tickets cost ~AUS$1,800.
